Here's a good topic. List anime you like and then name the best part and the worst parts about it. By the way if you have "Nothing" to say for Worst, then don't use that anime. Makes the topic too boring if you ask me.
Yu Yu Hakusho
Best: Story, fight scenes, great villains, great cast.
Worst: Genkai "comes back" sort of ruining the death. Last saga feels A BIT rushed. Animation in some episodes really bad.
Best: Action, characters, story, highly enjoyable soundtrack.
Worst: Some episodes take 3 views to understand. (it might be the dub though)
Best: Fun, imaginative. Great designs, characters, and music.
Worst: ULTRA Cheesy at times.
Best: Great epic, funny, straight out bizarre
Worst: Some parts really drag out, flashbacks are too long for my tastes.
Best: Action, memorable characters
Worst: LONG fights, HORRID filler (anime), Goku and Vegeta pass everyone in strength making everyone else utterly useless.
Best: Funny, great animation, character designs.
Worst: Too damn long to finish something so short. Washu wasn't in it until episode 5.
Best: Has complete story, still funny, still good character designs, Katsuhito and Nobiyuki got to be IN the story for a change.
Worst: Animation isn't AS good. Washu wasn't in the bikini episode. >_>
Best: Awesome characters, story, funny, designs, music…
Worst: Animation changes from episode to episode, sometimes for the worse.
Bubblegum Crisis (original):
Best: Freaking awesome soundtrack. Animation is great, and still holds up. Great Japanese voice cast.
Worst: Short. Some parts in the first couple of episodes drag a bit. The dub voice acting.
