Holstra Boring, long, and too preachy.

SparkMore n my opinion it was a great movie with some interesting elements, even though having some plot holes and the ending probably was just too messy and crammed together, but still fun to watch and not your casual movie that is similar to all other ones.

Myron Clemons A film of deceptively outspoken contemporary relevance, this is cinema at its most alert, alarming and alive.

Ella-May O'Brien Each character in this movie — down to the smallest one — is an individual rather than a type, prone to spontaneous changes of mood and sometimes amusing outbursts of pettiness or ill humor.

cinziabloom 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.

asurans Overall, this was a pretty good movie. The plot was a little predictable (ironic) and there were several continuity and logical errors made. The biggest was simply the time travel concept. Changing the past for one person changes the future for everyone on the planet immediately. Instead, it took a few trips for the effects to be made evident. On the flip side, a good bit of the science was good and correct. Seeing one's self in the future from the past (entropic cascade failure), you being the only one(s) to remember past events that now never happen, etc. This was all theoretically correct. But their problem with finding hydrogen? That is a simple science. Water and electricity. Considering the amount of power going into that device, some of it could easily have been siphoned off for hydrogen generation. Oh well. Also- the instances with the camera. If he went back in time to destroy the time machine, then by the rules of causality he would disappear along with the camera and time machine (the movie only did the character and time machine). Somehow, the camera stayed there for who knows how long until the tape expired. Then, it presumably kept running until the battery went dead. The fact that he was able to turn it on in the future and the "original" from that timeline suggest this line of events essentially is repeating itself over and over. Based on this prospect, it could be assumed that the entire universe/their entire reality is stuck at this point in time and never moving forward- only going back on itself multiplying the number of times this kid recorded the series of events and then going back in time again to destroy the equipment all while leaving the camera recording and waiting for the next future self to turn it on, watch it, and repeat the series of events again in an infinite loop. Wow. That was a huge rant there, but enough said about that. Anyway, good movie for the action, but it could have been better on fixing the continuity and logical mistakes.

pastorjk I'm by no way a fan of the found-footage genre, it sucks and is very annoying. However, this movie is good. Now, those who are looking for science instead of a movie (which I'm not sure why those types would be watching a movie to begin with), this might disappoint. However, if you don't take yourself too seriously and you can actually watch something and your not so anal retentive, then you should LOVE this movie. It's gotta neat little story, and the characters are adorable. It's fun and it doesn't take itself too seriously. It's good, clean, "Entertainment"!

LWSheffield It doesn't take long to review any film Michael Bay has been anywhere near so I'll keep this brief. Remember the early 'Transformers' films? Shia LaBeouf's nerd character inexplicably gets with Megan Fox's over-sexualised mega-babe character. Its just that again with a younger nerd + babe - because these films are produced by 'dudes' who have to throw in the creepy scenes where they zoom in on the girls' tits, asses and legs and we all have to leer along with them because its just dudes being dudes - even when they're nerds. After the first third of the film replays Transformers for us, we are then treated to the second act of overlong experiment scenes and super-cool time travel experiences which go to the trouble of highlighting every issue they could think of with time travel, and then go and create some inexplicable paradoxes (how does he go back to the wall to kiss her when his past self is already there? why when they replay the classroom test scene do they not run into X amount of their past selves, also trying to replay this moment?) Then finally we get the third act, which can pretty much be summed up in three words that never needed to be the blueprint for anything - The Butterfly Effect. Somehow every combination of effects they have on the past directly effect their present in a negative way - shock horror. The film limps to a predictable end by tying up the mystery of the key ring that had everyone on the edge of their seats for all of 3 seconds. By this point you will be exhausted by all the questions this film raises and will just be glad its over, not caring that none of it makes sense.
