I had trouble enjoying it even as a popcorn flick. Ryan Reynolds and Jeff Bridges worked together well, but I'm not at all exaggerating when I say that it seemed like the two of them were just ad libbing banter back and forth for half the film. I couldn't shake the feeling that so much of the legitimately good stuff was something not even in the script in the first place.
Also, RIPD does NOT have the worst CGI of 2013. That honor goes to Olympus Has Fallen. That movie is embarrassingly bad. Star Wars Episode II was better, and that is not an exaggeration in the slightest.
