This distinguishable idea was used before and that is why the wow! effect is smaller; the backgrounds are different, but there are lots of similar features: mobile phone calls, hope vs. despair via events outside, new sudden twists, the fate of the leading character etc. However, Stephen Dorff is stronger and more versatile actor than Ryan Reynolds.

I have heard that many did not like the ending scenes - but I did not mind; in my opinion, it would have been more shallow if the pre-ending scenes had taken the form of the final solution. However, it remained unclear to me who was involved with whom etc.

A catchy thriller if you like movies with solo performances in a limited space.
