I actually like the second one better. Maybe It's just the music. Hell, even the theme was better in Ghostbusters II. Out
The first one is one of my all time favorites, and easily my favorite comedy. The second one is really enjoyable for me and brings back fond memories of the time it came out, but overall I would say it falls short of the first ones quality. In the end I love them both though.
The first GB 1 is the BEST I think cause GB 2 didn't really have as much in it that kept a person interested in it.
