Watched it on opening day and loved it. Is it full of fan service? Yes. Would you watch a sequel to a 30 year old film if it WASN'T going to take you back to things and people you loved about the original? No. So I don't see it as a bad thing. Amazing new cast, a good story, good jokes and enough easter eggs for even the most hardcore Ghostbuster. It's the 3rd film we all wanted and deserved, and I loved the new generation of characters.
