Ok, I realized a lot of characters had bad/downright sucky Final Smashes or Ways to avoid them. Here's a list: (Note: These are from actual info, as seen in videos, by reliable sources (such as BrawlCentral, and by Dojo)
Kirby: According to a few sites, you can hit Kirby from a safe distance with a projectile to rack up his damage during his attack. Also has the chance of not cooking up anybody.
Pit: The Centurions are easy to hit away with moves such as Mario Tornado (which is not Mario's B move )
Sonic: Hard to control
DK: arguably his WORST attack, has a very small radius, even when fully powered
Peach: Kirby, Dedede, and any Gliding players can simply stall in the air, each the Peachs, and KO the Princess.
Fox: The Tank is very large, and your opponents can hang out right in front of it and be invincible
Diddy: Supposedly this move does more good then bad. I hear it's better to launch the peanuts into a gap or something.
Meta Knight: Extremely Low Hitbox.
Dedede: Waddle Dees do very little damage according to Whobby's (or however you spell it) Demo
Ice Climbers: All ICs can walk on the ice, not just the pair that did the Final Smash
Wario: This one is self-explanatory. Does this even count as an Attack? It's like a Power-up.
Pokemon Trainer: The Pokemon can't hit behind them or change the direction your facing. You could be stuck blasting off at the end of the feild, where no one is even close to.
Pikachu: Very hard to control.
Names Not listed: Mario, Link, Yoshi, Lucas, Ike, Samus, Bowser
The fact that only a few of them are actually "good" final smashes is sort of sad. These may be inaccurate, someone please tell me if so.
