Cowboys & Aliens
Half of a pretty good Western awkwardly welded to a really dully, really cliche scifi-action movie. That pretty much sums up everything here. The first 30 minutes or so are really good, but it gets dragged down by the introduction of aliens and lots of CG battles chocked full of random explosions. The last 30 minutes [i.e. the final battle] is DUUUUUUUUUUULLLLLLL. Craig and Ford lend far more credibility to this movie than it deserves, but Olivia Wilde is nothing more than a pretty face. It's not awful, in fact it's better than a good number of major blockbusters [transformers], but it's just...not good. Whacking off the scifi part and just making a straight Western likely would have resulted in a much better movie, though it would still have been written by Orci and Kurtzman, so maybe not.
Also, lol @ Nolan-haters. Get a life loosers.
