Now sometimes there is one aspect that may sway you to actually enjoy something more than others. In this case it may be the bike riding and the "stunts" in general. I read from another reviewer that this is losely based/inspired on "Le Prince Noir" (Black Prince). I have not seen that short (which is b/w according to the other reviewer) and has really good cinematography, style wise similar to the way this movie was shot.
Having said all that, the plot here is really nothing you haven't seen before or anything you will remember for long after you've seen the movie. So if you like the way the bike scenes are filmed, good for you, otherwise you may be underwhelmed by the movie overall.
