Perfect cast and a good story

It's a good bad... and worth a popcorn matinée. While it's easy to lament what could have been...

Through painfully honest and emotional moments, the movie becomes irresistibly relatable

It’s fine. It's literally the definition of a fine movie. You’ve seen it before, you know every beat and outcome before the characters even do. Only question is how much escapism you’re looking for.

If you are a fan of bad camera work and direction plus annoying teens that can't act then this maybe for you. A good idea for a movie spoilt by childish themes, amateurish acting, poor direction but most annoying of all is the cheap hand-held camera work throughout. I only managed to watch 3/4 of this drivel.

As I finished watching it, I felt disappointed: plot holes, not so strong plot, crazy shooting (ok, it's meant to be "young" footage-style, but... exxagerated!) ...One day later, it feels a bit better. I am still a bit disappointed by the shooting but... ok. On the other hand, the plot now seems to make some sense, and even a complain I read somewhere about "they get a time machine and can't think of a better use"... becomes less critical. I mean, they're 17 or so: me too, if I had found such a machine back in the days, would've probably done the same choices!So, a somewhat nice idea and somewhat new. Acceptable.

This reminded me of Aston Kutcher's Butterfly Effect, which I think was a better version of the time-travel type movie. It's just amazing how everything is connected to everything and how Einstein could possibly come up with the Chaos Theory. It makes you wonder if something like this could ever become a reality in the future. Casting in the movie was good.. good screenplay and direction overall. A good movie for science buffs.

I need to comment on the review above from the so called "Engineer". He bashed this movie because he felt that technically it wasn't up to his level of academic standards. First off they didn't make this movie so that the Engineers in the world could take notes and use them in their jobs. This was a typical teen movie which kept your interest and had a decent ending. If you wanted an educational movie than maybe look into watching the education channel or maybe even the Sci-Fi channel. Why would you be watching a teen movie to compare your knowledge with what they portrayed in the movie.The movie is worth watching especially if you have teenagers. I have two that I watched the movie with an 18 year old and a 15 year old and they both enjoyed it. We were not going into watching this movie to learn how to time travel, and or build instruments. Hope this helps.
