My only issue with that movie was the timing of a few jokes (they made them longer than they should so they stopped being fun) and that the trailer spoiled half of the jokes. The movie itself is cool.
The newest ones? their only redeeming quality for me is Egon's granddaughter. The kid is really good. Everything else is just the dumbest nostalgia bait ever (even having the mom's boyfriend a literal stand in for the kind of fan the movies pander to).
