I really don't find Tom Cruise to be that bad an actor, honestly
I just looked at my review that I posted when I watched the film in theaters... I described it as feeling a bit like "
Moon on a larger scale meets
The Terminator with the visual style of
Tron Legacy".
I actually found a lot of the philosophy intertwined with the story to be quite interesting. It wasn't particularly revolutionary, per say, but it was handled very well and was quite intriguing throughout.
