He pretty much hit it spot on.
Ghostbusters is 'fun' just because you get a proton pack and can blow sh@# up! But all the problems he listed are there:
1. wacky script with lame comedy (and Bill Murray just doesn't seem to have any emotion in the character, like in the movies)
2. the "retard round up". Seriously the lamest part of the damn game - running around picking up your AI buddies cause they can't dodge. On top of that, if you get knocked down, you're stuck there until one of them decides to help you out (which can take awhile). And then there's the situation where if you are knocked down and your teammate picks you up, then suddenly they get knocked down, so you pick him up and get knocked down in the process, etc etc etc.. there are several times that can happen and it just sucks. Sometimes the easiest way to win a boss battle, is to just run around picking people up and dodging attacks - never firing. What makes it worst is you can only take like 2 or 3 hits after getting up from a knockdown.. and if there's 4 ghosts throwing junk at you, you go down fast.
I made the mistake of buying this game. This is definitely a RENT game! I know that, now I've completed it, I probably won't play it again since it has low replay value. (HOWEVER, I never messed with multiplayer.. so maybe I should give that a try before boxing it for good)
