I watched it the other day... and it entertained me.. I was expecting much because.. well it's Mission Impossible.. as people have said the plot is obvious and so on..
But I went to watch it and we only decided to watch it about 5 minutes before the movie started.. the cinema was empty and I thought it was a fun movie.. again Philip Seymour Hoffman was a great villain and I thought Ving Rhames was great to.
overall not a movie I would watch often but for people who just want some good action and a few things blowing up.. it is a fun watch.
