Is there a movie in a series that you find yourself skipping?

I was sitting here going through some movies that I enjoy watching and came across the Mission Impossible series. I tend to, not always, but skip the second. It really doesn't add to any of the others in the series and I recall watching it the first time wondering if it would kill the series all together.

I also think of any third movie in an X-Men series. They just tend to be bad. Every so often I'll watch it again thinking, maybe this time it won't be so….Oh, oh no, no it is. This isn't what I want.
