It's odd. The new character, A.B.A., seems to suck in a target rich environment, which is exactly what the game is about. Her design's ok, but not too many details can be seen in her in-game frames.
The last boss, Leopaldon (or something) isn't particularly memorable. It's a cross between a yeti, a whale shark, a hippo, a polar bear, a wizard, and a puppy dog with goggles. It's not a personality, like Justice, I-no, or Dizzy, it's just beast. It also breaks the tradition of having a female last boss.
Also, I hate Baiken's recolor. She used to be a reference/homage to Kenshin, minus one arm, one eye, and plus two breasts, but they colored her pink hair red, turning her into a flat-out copy. At least you can load the old color schemes.
