Kinda sad really. I know they get a lot of crap, but I always felt the first and third one were decent enough. The second and forth were complete and utter trash though. Maybe I was hoping it was going to pull an odd = good, even = bad sort of thing. While I might have hoped for the best, the fourth movie pretty much made me go "Ahahahahahaaha nope." so my expectations were pretty low.
You know, I have a soft spot for shaky cam stuff. I know a lot of people hate it but I always liked the general feel of it overall. That said, there are very few shaky cam movies that I like because most tend to be crap.
