Well, I'm going to whine and complain a little myself.
My problem isn't that there are clones in Brawl. My problem is that they saw fit to clone Fox twice. I mean, if they were going to add another clone, why add Wolf as a Fox clone? Where's my Samus clone, or my Peach clone. I mean, it's not like I'm asking for a Game & Watch or Olimar or Ice Climbers clone (those would be super fucking sweet). I'm not even asking for a new original moveset, I know that takes a lot of work, but Tetra in as a Zelda clone (except with a different Down Special) would have been totally acceptable.
It's not a deal breaker or anything, but it is disappointing that they decided that Fox, of all people, deserved to have his moveset repeated 3 times, yet we couldn't get a second Ness clone (okay, I know that's not realistic, but a second Mario clone, come on).
