Extremely disappointed with the final roster overall, most notably Baby Bowser, Dark Pit, Lucina (Yes she's cute, but what else besides being another Marth?) maybe one or two i'm missing. Partly disappointed by the lack of highly requested characters such as Krystal (Star fox adventures), Zelda characters, Issac and a few Golden Sun characters that could have been added. Krystal and those Golden Sun characters have the "look" of a top tier too, not a character that you get the feeling is weak just by looking at them. That seem fierceness that Fox and Falco brought to Melee, even if you were a casual you knew they didn't suck. I dunno, i'm ranting, sorry.
Lots of reused assets too, past stages don't even feel like "past stages" anymore, more like... " Sakurai hurry and do what you can to finish Smash Bros as soon as possible but at the same time making the game not look empty, we need it to save our Wii-U, we know and even the fans know, this is our biggest trump card. *proceeds to reuse past stages like no tomorrow* sorry still ranting.
