The Dr. Strange movie needed to be about 20 minutes longer, but is decent, and the Ultimate Avengers movies are basically Ultimates run through a filter of 616 characterization. I saw them first, and was very disappointed when I went to check out the actual comics, because the movies had led me to believe I'd be getting something much closer to the people I knew from 616 canon.

Warning for character death in the second film, but it also includes T'Challa fighting shape-shifting Nazis, and Thor jump-starting Tony's heart with lightning. edit: Thor is probably the closest to his Ult-verse self, which since he's the best part of Ultimates #1, is awesome.
