Well, more so than wavedashing, I don't like what they did to air-dodging... I prefer the ability to air-dodge in a direction, and I liked how Melee ran faster and was less floatier... also, a lot of the new levels in Brawl are kinda crappy, I was disappointed with them... New Pork City and Spear Pillar in particular are 2 of the worst Smash levels ever. But the amount of content and awesome new characters puts it ahead of Melee for me. Not as perfect as it could have been but still fuck-amazing.
