Went to see Guardians of the Galaxy with some friends, on a whim. I was not at all familiar with comic and had no idea what I was going in to. I actually thought the beginning was a trailer, took about 3 minutes to realize the movie had started.
That being said, I actually liked it a lot. I thought the sheer number of bad guys was at times confusing, but the idea was pretty clear. I thought the character interactions were cute, had some lawlz. Really, really, liked the graphics. It seemed that at times instead of trying to use CGI to make something impossible look "real" they just changed mediums to comic book graphics, paintings, or just straight obvious digital, thought it was well done and very pretty. Some solid fighting too.
The Avengers tie in was pretty sweet too.
Story on the whole was kinda whatever, but I never go into comic book movies for stellar plots. Just a bad guy and guy guy will do.
