This is very cool. It's basically a music video that was used to hype up the show. There are lots of small changes between this video and the actual show such as the uniforms all being the same color and Slimer's personality. You also get to see where they got all the scenes for the opening title sequence in the real show. 

Woah. That IS cool! Nice find mass. It's weird seeing the guys all in the same colored outfit (even though that was the case in the movie). If I were a studio exec, I would have been ready to greenlight this. Apparently that was the case.

I've seen this a while ago, actually. I like how things were kept closer to the movies in terms of design. Such as the regular suits from the movies, Slimer's onionhead design, Peter Venkman looking closer to Bill Murray's character. Is there anything else I'm missing? Probably.
