At work at the moment, so watched it without sound, but still thoroughly enjoyed most of this film.
Of course, my opinion can't be completely relied upon without me having sound and everything, but I felt the (trying to think a way of addressing this without creating a spoiler) event was a little simple. In fact, it relies on a commonly used cliché about tomorrow and buses.
This is an interesting theme, one anybody who has had an unsatisfactory job can relate to (i.e. most of us at one point or another), and because of that, I feel it needed to undercut expectations more than it did. I feel the event used would have been the first idea someone would think of as a possible disruption to a life like this, but if there had been a bit more brainstorming (shit phrase, I know) something much more poignant and profound could have been discovered.
So, film making (from an imagery point of view) I really liked it. Story could be better. Great first film though!
