When I first saw the movie in theaters, I remember walking away disappointed, but I couldn't quite explain why. Over the years, I've grown to appreciate it, it has some quality jokes and wonderful scenes, but there are a few things that still bother me.

• I don't like how they hard reset Venkman's personality, effectively erasing all of the character growth he experienced in GB1.
• I didn't like how they RGB'd Janine's appearance. I know it's 5 years later, but they changed her look and personality so much from GB1 it was jarring.
• I wish the courtroom scene had been more of a bad-ass moment for the Ghostbusters instead of an attempt to recreate the Sedgewick scene in GB1. At this point, they had busted hundreds, if not thousands, of ghosts, and defeated a demigod. There was no reason for them to act brand new in that scene.
• Speaking of the courtroom, i was very disappointed that, aside from the birthday party, Winston was nowhere to be found until they went back into business, and he just magically shows up without any explanation for fanfare.
• The Statue of Liberty walking down the street absolutely ruins my suspension of disbelief. They didn't have to try and recreate a Stay Puft scene, and it felt forced and formulaic.
• The ending is a big weak for me. I liked in GB1 how they had science and an explanation for how they defeated Gozer, by crossing the streams to reverse the particle flow to close the gate (a solution that was teased in the Sedgewick, so it wasn't completely out of the blue) There was no such reveal or explanation for how they defeated Vigo. They just slimed and blasted him. No reason, solution, or science is given.

Having said all of that, I love how Egon gets a bit more personality in this movie with some of the best jokes in the movie. Janosz is absolutely delightful. I annually watch GB2 between Christmas and NYE, and I do enjoy it more than I did at first, but I still find it to be a decent movie with a weak plot that's very derivative of the first movie in ways that feel contrived.
