There's a difference between something that's boring and something that just sucks. There's plenty of films that can be boring, if you're not really willing to commit to them (or even if you are, they just seem to drag on), but you could still see some merit in them. Equally, there's plenty of films which don't have time to get boring but just downright suck.
But if I was going to pick something I found boring that lots of other people seemed to love, it would be the Avengers movie. Seriously, that just went on and on and on.
