I think I've seen all of the House films but only really remember the original.

If you liked the first film you would definitely like the second if you wanna give it another watch. I really liked the different direction the third film took but not everyone would. The fourth film was a bit weird I can only vaguely remember it.

I agree, The Horror Show(1989) is a very good flick.

I think I may have seen some bits of the third and fourth movie, they seem familiar.
