I am cautiously optimistic. I haven't really enjoyed anything Cruise has done since Collateral (although he stole Tropic Thunder, his character was awesome) but this sparks my interest.
This looks like it has the makings of a fun, pop corn action flick. Nothing heavy, nothing that will blow us away, but it at least shows some potential to be entertaining, even though the concept and story don't look to be original at all. I don't demand much from my action movies, just be on pace, have good action, and a story that doesn't make me roll my eyes too many times.
