Captain America is completely unremarkable. Its just there. Watching it keeps you occupied for two hours but I've had more enriching conversations with my dog. It does nothing that other films haven't done better. Its not a bad film, just a tremendously bland one.
Conan's reputation is beginning to speak for itself.
I recommend you stay in and watch a good movie on DVD. The King's Speech is pretty brilliant, as is Frost/Nixon, The Madness of King George and Peter Sellers masterpiece "Being There".
Watch one of those instead. That's what I think you should do.
