I actually agree with bob on this one. I thought the first was average and that this was too. Just forgettable action films, with the first being bit obnoxious and this one being a bit dull. I also like how the deaths of MILLIONS of people in the climax is papered over with "and the world rebuilt" at the end.
I would say, wait for it on DVD and rent it from RedBox...if you're a fan of Joe and just curious. Otherwise, pass.
