I hate that feeling. Not knowing if the name they just mentioned is someone important I forgot about or the director is going for a convoluted timeline and they are talking about someone we haven't seen yet.

I have better things to do than watch movies with the risk of not understanding them. It's like saying to read a book "generally." What a waste of time.

But it also depends on the genre. If you're a fan of blockbuster action movies, most dialogue is unimportant anyway. If you enjoy drama or more artsy movies, you probably need to follow what's going on.
