Hey, it's just a fun, mindless romp of urban science fiction with a great plot, decent directing, some sketchy dialog, good and bad acting, and you can even write a love poem while watching it and never miss a thing.
There is even a very 'Ballsy' stoke of genius in this movie, in that the scene from about 104:12 to 110:12 is a continuous shot. 6 full minutes. That took guts. I have to respect anyone who would do that and be willing to risk the whole movie. There was obvious no real risk here, and that's probably why it worked.
For the whiners out there who constantly wail: "I want my 2 hours back!" "Worst movie ever!" "I walked out in the first 10 minutes."...Just shut the hell up. You really do NOT how to watch a movie using basic 'discernment' techniques rather than judging the hell out of it like an old, angry housewife.
See, discernment allows an evaluation to grow while a judgement puts an idea or concept inside a contemplative box where it can never evolve beyond that place within your own mind where you originally judged it. That is indeed the most wretched excess of a personal 'opinion'. It wastes everyone's time and energy. You reviewers who prattle on like wounded princesses here are seriously lacking in the most basic of intellectual evaluations skills and shouldn't even be posting your reviews with educated adults. Jesus...
So, in regards to ANY movie, when you see the trailer and read some professional reviews, you pretty much know what you're in for. But anyone who plays the 'princess-victim' of utter disappointment after spending a dollar at Red Box seriously needs to ease off the meds.
...or at LEAST take some creative writing classes.
