You've watched the movie several times. It's quite possible that what's boring you isn't the character - it's the story. You have two options; wait for IM3 to come out and see how you feel, or start reading the monthly comic. Be warned - there's a lot of backstory for the comic if you hadn't been reading it already, and said backstory is only tangentially related to the movies...
