Roar of Time looks like it's attacking with a bunch of cheerleader pom poms...
Solarbeam's attack animation has been displayed wrong. It suppose to be the Pokemon shoot the beam towards the opponent, not the sky.
I thought of a few more.
Hyper Voice in Gen 4. There's like an awkward pause between the shockwave things. It looked a lot better in gen 3. Also Swift in Gen 4 and 5. In previous games it looked like ninja throwing stars or something, but now it's this really sparkly, non-threatening attack.
Tail Whip. It doesn't even do anything with its tail. It just sort of... shakes around a bit.
I also hate how Fly and Bounce now look like your Pokémon turned into a bubble and floated upwards. It's like "What?"
Then there's Outrage, which was cool in Generation III, but then in Generation V, it just looks like a spiral coming out the user's back, which is disorienting because when you're using it, it looks like it's been used ON you, and when it's being used on you, it looks like YOUR using it.
Also, Splash Attack. How cool would it be if it caused mass tidal waves and energy to shoot out of everywhere and generally just look like a really huge attack and then despair as you read "But nothing happened."
I don't like the final part of Frenzy Plant's animation. It has the same problem as Doom Desire's; great build-up and then a non-painful looking attack.
Non-painful? A bunch of tree roots burst out from under the ground to unleash a devastating pummel. o_o; At least in PBR, I haven't seen Frenzy Plant in the DS games yet...
Replaying HGSS reminded me how how silly Sacred Fire looks in the DS games. D: Purple flames, nice. But the background is really what gets me. It's just...kinda...it's just there. It should look more epic.
In the DS games, the roots just sort of appear slowly after epic build-up, then the target shakes and green stuff appears.
Frenzy Plant (move) - Bulbapedia, the community-driven Pokémon encyclopedia
^ There, though the animation isn't as slow in-game.
DPPl's Spacial Rend looks kinda lame for Palkia's ultimate attack. You'll expect something more exciting, but at least the background is pretty. The anime doesn't do the move any justice either.
Fly, what the actual f***?
And as for Sacred Fire, I can't even, the purple fire is nice, as said above, but it's not purple in any other media, and it's a physical move...
Dig's animation... I'm appalled, I still think your mon should emerge in the other pokémon's ''field''
Also, even though I love Gen III, I have to admit, their Solarbeam and Hyperbeams are stupid, DNA BEAM!! I now want this move
Bulbapedia is having some problems right now apparently, so I can't look it up, but I think it's Gen V's Earthquake animation. It just doesn't even look like an earthquake. All the previous generation animations were fine for it though

Don't mess with L!
That freaking Night Daze...
In the anime, it was this amazingly awesome explosion of crimson-pink energy blasting everything in sight! In the game, it's just this weird purple thing that looks like water ripples, WTF!?

Magical Leaf. It just shoots rainbow leaves at the enemy and when it hits it looks...weak. Looks epic in Gen 3 though.

hippiepsychic power, so I thought it all looked pretty cool... plus pretty @3@ - But yeah, in Generation IV and V, it doesn't even really look like the leaves are actually attacking him. It just looks like they're just sort of existing next to him.
