Typically things I look for are a movie that's pushed like its a big budget film but doesn't have any actors I've ever heard of.

Too much expositional dialogue at the beginning of the movie especially when its so foreign to the way people talk in real life.

In the new Star Wars movie, the "can you hear me now?" "joke" in the first 5 minutes.

Unnecessary sequels to a completed story.

I'm sure there are others but my break is over and this is all I could think of.
