Saw it this past weekend. I thought it was OK. As has been said on this thread, the main villain had a feeling of “been there done that” mode, so I didn’t find him particularly special. Truth be told, I found Chris Pratt’s character rather one-dimensional as well, especially going up against the rest of that group. Pratt seemed more animated (pardon the pun) in “The Lego Movie”!
Now, I have stated before that I am not learned in the ways of comic books, and I must admit, I was not even aware of “Guardians of the Galaxy”, so I am not sure if Peter Quill’s character is depicted exactly as he was in the comics.
Using Leonard Maltin’s rating from his movie guide (RIP, by the way), I gave this feature *** stars, albeit, not a strong three.
