Captain America: The Winter Soldier

Were we supposed to know going in who The Winter Soldier is?  Is it a comic book thing, where anyone who knows the comics knows this dude's identity?  Cuz all the previews made the reveal scene a bit anticlimactic.  Fitting perhaps, regardless.  Because this movie was a bit anticlimactic.   Kinda felt like it was trying to do a Bourne Identity thing.  I have nothing against Bourne Identity things.  But when I've paid money to see someone named Captain America do stuff, I'm not really expecting the stuff to be so action movie de rigueur.  Verdict: Movie Rental (or just see Captain America again)
