Saw Ghostbusters myself, and I have to say...what the hell is wrong with Sony's marketing department? They basically put all the worst jokes of the movie in the trailer, or alternatively, the ones that didn't suck were ones that only work in context which is to say they would seem like forced humor otherwise. Because seriously, there's plenty of good stuff you could have shown, stuff that didn't even need context, in the trailer that would have worked.
So yeah, I enjoyed it overall, think the last time a movie looked absolutely awful in a trailer but was way better in practice that I saw was Baseketball, though in Baseketball's defense, I don't think it's possible to make that movie look good in a trailer, given it was made specifically to be a movie about the dumbest idea you can think of.
I won't say it's a perfect movie, or anything like that, but watching it did make me realize "This is exactly what a reboot should be", at least in the sense of the direction the movie took. Now yes, they had a bunch of callbacks to the original, but that's very much a "damned if you do, damned if you don't" scenario, so whatever, but overall, it recognized the basic premise of the original movie, but tried to be unique and original, not simply "Same movie but gender swapped lol." Considering that, it really begs the question why the trailer further tried to evoke imagery of the original movie so much; showing that the initial ghost encounter appeared in what looked like a library was NOT a wise idea in the slightest, since it basically says "we're trying our hardest to evoke nostalgia damn it!", when most of the movie doesn't do that. If you're going to do a "reboot" instead of a "remake", you need to bother to actually change things up a lot to justify you're re-establishing a setting, new rules, etc., such that you can do your own thing with the same basic premise, which this movie does for the most part.
So overall, it was fun. Not sure I have any intention on seeing it again, but I don't regret the time I spent on it; it's a lot like Men in Black 3 in that regard.
