Sometimes, but it's not as bad as it used to be years ago. most of the time it stems from the fact of how the final product was produced, and how it could've been done better, which led to the producer (in those days, IGA) being constantly flamed. I distinctly remember when PoR was announced; some people were excited, a lot weren't, and one condescending quote that sticks out in my head is "Well, here we go again." It's no different than people hating on movie directors for creating lame movies (Michael Bay gets a lot of shit for his Transformers movies all the time). It's only recently that after a 5 year hiatus people are willing to accept another "metroidvania," mainly due to the dissatisfaction Mirror of Fate brought most of us (and the fact that many believe OoE was a step in the right direction where the metroidvania formula was concerned. I agree with that statement, but of course it's debatable).
We've all been guilty of that sort of thing, and I'm sure you've done it yourself Montoya, since it's obvious you're not the biggest fan of IGA and what he's done with the series, thus you're going to be and have been vocal about it, as has many other members here. It's natural, and this is what fan forums are for, to express your feelings on the current situation on your favorite series. It's not just on this forum, or gaming forums, but every type of forum of entertainment.
It's not depressing, it's the internet.
