I came across this today and I hadn't ever seen it before--so I thought it was worth linking for anyone else who had not seen it either. Despite how every day seems to be a new chapter in how horrible everything is right now, it put a big smile on my face.
I watched them all but was never a huge fan. On rewatching the first one a few years ago, I thought it was an almost perfect film and very entertaining. I enjoy the sequels too. I just forget 95% of what happened in them (which is good for re-watching after a few years).
I have very fond memories of seeing PART III in Signal Hills Mall in West St. Paul MN back in 1990! I miss that Mall btw, I was there a lot when I was a little kid back in the early eighties.
