Saw it tonight. I enjoyed it. I enjoyed the two cameos from the previous films.
This movie had a ton of character actors--"That guy"s, I guess. Oliver Platt, Matt Craven, Michael Ironside, Ray Wise, Glenn Morshower, James Remar, Brendan Fehr...plus one of the military guys in the US "War Room" was recognizable but I don't recall his name.
