Yeah, I've heard that too.
I saw Resurrection in the theater and then again about 17 years ago. It's a weird movie and I remember a few of the jokes more than most of the rest of the movie. It's not really good but I don't remember being bored.
I bought the box set because I wanted the first two movies and all the extras, and I wanted to see the longer version of 3, which meant I should also rewatch the original. I'm not going to rewatch 3 and Resurrection over and over, but the set was still the best price for what I was looking for.
Quadrilogy is on bluray /multi format (why is the multi-format cheaper?)
but it doesn't have all the bonus material than the Anthology I bought has.
