Akroyd's insanity would have given us a movie about rival gangs of Ghostbusters traveling between dimensions, you can thank the rest of the gang for holding back Akroyd's insanity if anything.
Actually you can thank Bill Murray for the final product. The original Ramis/Aykroid script wasn't nearly as good, and most of the improvements came from Murray.
Yeah, man, they made absolutely nothing but good movies back then, it's not like you're only remembering the good movies while forgetting all the bad or anything.
Have you looked at that list DESSERT? Jesus, it's amazing. The only movies coming out I'm looking forward to right now are Harry Potter and Machete. Just, damn....
Hahaha. Memories. I actually watched this again on cable a few months back and was surprised by the special effects... not that they were anything amazing, but that they weren't as bad as I would have expected them to look after 25 or so years.
