I was also bored for the 3rd act of Batman Begins because I didn't find Ras a compelling villian. Compelling mentor, yes. Compelling villian, no. I was looking at my watching wanting the movie to hurry up and finish. Liked the Joker card reveal though.
Then most people would have a good reason to dislike classic films like 2001. Being bored is very relative and varies from person to person, that may affect entertainment, but it's not a good argumente for how something was bad, maybe the factors of the film that lead you to be bored are. Like the film dragging too much or other flaws.
