In Shawshank was Andy a perfect protagonist or was he flawed? Why? Give an example. Was he interesting?

I didn't really see much of the movie so I don't really know but I'd say he's pretty good as protagonist but not perfect because the characters in the movie, including him was really boring, it made me want see whats gonna happen next but I wouldn't really re watch the movie again because it just doesn't feel chill to watch.
