There’s a good chance all the extra scenes with Louis didn’t jive with the rest of the films. I know us as fans would have loved to see that kind of stuff, but you think about it from Average Joe’s point of view and a sub plot of some nerd with a proton pack dosn’t seem all that interesting.
I’m willing to bet that a scene like the one cut from the film of Louis hunting Slimer screwed up the pacing all kinds of ways and was thusly removed. It also might have not tested well with audiences. I for one want to see more GHostbusters, not Louis Tully Attorney at Law.
