A little too over the top on the forced humor IMO.
This one seems to be trying to be what Ghostbusters 2 tried harder to do... Be too much of a comedy rather than a movie about ghosts and ghostbusting... And this trailer shows they even go farther.
The original is just a great movie in that the humor is very subtle in most cases and it usually played off more seriously. I mean, some of the things they say ( especially Egon) sound funny, but it all comes off as serious to the person who said it.
I was never against an all female cast. I understand that as soon as you throw a mixed sex team in an adultish movie, two of them are going to end up in a relationship by the end of it and ruin the team dynamic (Unless one of the members of this team was a gay male...) But they are reaching very low with the stereotypes on this cast, and it certainly is not helping.
I was kind of hoping that maybe. Just MAYBE, they could have done something at least in the same tone as the original... But this trailer clearly shows that they are not.
