To start, I'd like to make a perfectly casual, and completely complimentary stark observation, as evidently clear as it may be that Dan Aykroyd seems like a really horny dude. Jon Lovitz too. Omg, look, it's a young cute Alyson Hannigan! Me too. I've never watched My Stepmother Is an Alien before and I've usually seen a movie at least once before I go into writing a review for it, but I only seen that one hot scene with Kim in the bedroom (obviously) in this years ago that I somewhat remember where she's wearing like a white negligee or something and I'm definitely looking forward to that scene again now and anything else My Stepmother Is an Alien has to offer. Kim Basinger in this makes me horny. I'm watching it now, Kim is gonna be the best part of this movie I feel, so far, so right. Mystic Pizza is the only other movie I reviewed while watching it the first time, thus explaining the review title and this sentence. This is a good, cute, funny, sexy movie that I think I already knew before watching. Hold on for further comment...I'm enjoying the movie. Oh, look, a little one-eyed alien in a purse. (note to self - potentially use little one-eyed alien in a purse reference momentarily when discussing that hot upcoming Kimmy scene I'm so looking forward to, or anything else that My Stepmother Is an Alien has to offer) Kim doesn't talk a lot in this. She's busy learning how to kiss, and relate. Thank God for it, genuinely, I love it. (note to self - resist urge to use little one-eyed alien in a purse reference now as Kimmy kisses up on Danny boy and stuff because you may need it later you doofus!) This scene reminds me of her from the end of Batman when's she's kissing up on the Joker trying to distract him in that bell tower. Okay, now she's talking more. Thank goodness. I love you Kim Basinger. It's not even fair how sweet and gorgeous you are it's really not! Watching the movie still...you remember that Wayne's World sketch where they'd do the Top Ten Hottest Babes, Kim Basinger would be my number one top hot babe, ch'ya, Kim breaks the human mold for epic hot babe sexuality like she's an alien from another planet or something, as if. (do you remember Kim from Wayne's World 2?! I almost forgot) Oh, she has to learn about sex, that's funny. (note to self & to you - i think the scene is coming) Oh here's the scene.....................speechless with my mouth open just like Dan is. OMG this' way hotter than I was expecting. That's definitely not a negligee........My Stepmother Is an Alien = Kim + sheer white nightgowny thingy / my love x her beautiful passion. I set myself up to be all cute towards Kim then she bombards me with her explosive sexual hotness. That's not fair Kim you goddess temptress enchantress you! That's eeevil. Do people know how hot Kim is in this, holy God? I love her. Oh yes. Kim's sweet sexual spiritual essence formed into actual beautiful womanly embodiment ramming into Earth's airy atmosphere during a rarefied and special solar moon phase one 1988 eve for My Stepmother Is an Alien. That actually happened one December 8, 1953 eve when Kim was born. Ah, the universe's most precious gift, horniness. I want to stick my little one-eyed alien in her purse.

Although this is (kindly) a "B" movie, this is one of my top ten favorite films. Most comedies produce a smile or a chuckle, but very few (like this one and Mickey Blue Eyes) produce an lol. The scene where she learns about kissing, the one where she walks outside in her bathrobe, the wedding scene where she dashes out to unbury Bag, and the scene where she prepares breakfast are hilarious, and I laugh even though I've seen the movie a dozen times. My favorite line: "Oh, I'm never coming back" is one I have used many times with friends and family. I own this and I watch it whenever I am in need of a good laugh!

Single dad widower scientist Steve accidentally sends an intergalactic zapping thingie which will destroy the planet at the other end unless he sends another one. As he doesn't realise he did it, they send a representative in the form of a hot woman (with a hostile handbag),and he falls for her and marries her. Hi-jinks ensue.This film is very silly but, if you are happy with silliness, it is quite good fun. Dan Aykroyd is likable as the hapless scientist, and a pre-Buffy Alyson Hannigan does very well as his daughter: you can sympathise with her rather than wanting to hit her with a heavy object as is the case with so many movie teens. But Kim Basinger, as alien Celeste, is very funny indeed. It's a shame her gift for comedy wasn't used more.

Well, darlings - Here we go again - Kim Basinger plays Celeste Martin, the "dumbest-bimbo-of-an-alien" to ever set foot on the face of this goddamn planet.This so-called Sci-Fi/Romance/Comedy was obviously geared to totally capitalize on Basinger's chilling facade of beauty. And at every opportunity it did just that.You know, I, for one, am sure relieved that this flick didn't try to capitalize on Basinger's brains - 'Cause if that were the case we'd all really be in for the scare of a lifetime.Celeste's ridiculous mission here on Earth is to find the means to reverse the effects of a ray that was sent from our planet to hers, which has drastically altered the gravity situation there.Unfortunately, the idiot creator of this ray, scientist, Steven Mills (played by that big, fat, lard-assed, doofus, Dan Aykroyd) doesn't even know how the hell to re-create it. Thinking Mills to be a total liar, Celeste, naturally, resorts to (what else?, but) sexual seduction and (get this) the promise of marriage to get Mills to cough up the secret.Like, talk about low-brow comedy at its all-time lowest. There wasn't a single, solitary funny, or worthwhile joke in this entire film.You know, I had always thought that beings from other worlds would be of a far superior intelligence to that of human beings. But this flick proves this assumption to be utterly erroneous - Especially when you've got the likes of that bimbo-brained Basinger at the helm, as a space traveler.
