You and me both. I was so skeptical of Creed when I first heard about it. After that first trailer I thought it could be "ok," but after seeing it three times, I can say it's one of my favorite movies in the Rocky series, definitely up there with the original Rocky and Rocky Balboa. Great film. My wife isn't a fan of the Rocky movies (or sports movies in general; neither am I, honestly, with Rocky being the exception), but even she thought the movie was great.
My point was that it's unfair to movies like Mad Max, Creed, Star Wars, Jurassic World, and Ghostbusters, to hold them up to the near unreachable standard of their classic predecessors. I don't know how Ghostbusters is going to turn out quality wise, but I'm not seeing anything that looks like a Jem or Gods of Egypt style clusterfuck. I think the movie looks entertaining. More entertaining than I thought it would. I was incredibly skeptical about this movie when I first heard of it, and not because of the female cast. When the cast was announced, that actually raised my interest in the movie, because I think all of them are talented and funny, and have styles of comedy that can play off of each other well. In particular Kristen Wiig, Leslie Jones, and Kate McKinnon are favorites of mine.
I was impressed with all of the classic franchise revivals of last year. My skepticism was shocked. I'm willing to give Ghostbusters the benefit of the doubt, in particular because I actually thought the trailer was good. My concerns were actually alleviated after seeing this.
