I've seen the first 4 Twilight movies, mainly because they have Rifftrax accompaniment available. Do not see them unless you get the Rifftrax. Seriously. They are so fucking slow and boring. There is not nearly enough schlock to get any normal human being through these things. Michael Sheen is in the first 4 for maybe 15 minutes, I think? They are just some vampire counsil in a different country that the movies sometimes cut away to in between periods of non-events (all of the events, that is).

The first movie establishes things so it is bearable, though with generally horrible line delivery and facial expressions. It can be fun in the right mindset. 20 minutes into the 2nd one I just thought "Really... more of the same shit?", and at that point Rifftrax to the rescue. Some of them are barely watchable even with Rifftrax, they are just so slooooooooooooooow. You watch one of these 2-hour stresstests and once they are done, you will swear they were all in slow-motion, all the time.
