I dont think you should hate this game. Granted i think that the fighting moves you can do could be a lot better. But i had fun playing this game.
The game is good in my eyes, because if you watched the dragonball z series and gt series, it follows the story line quite well. Also it included re-animated cut scenes from the series which was quite refreshing.
This game also goes back to the old ps2 budokai games, to the point where you can free roam around the islands, and do optional side game battles, and you may also find the odd dragon ball lying around.
Overall the game has a good playthrough, and excellent graphics, but they just need to improve the actual battle style, because as a gamer you can only really do fight clashes, and you end up relying on the super moves to do some damage. But i don't think i wasted my money when buying this game, and urge anyone else to buy it.
But when you buy it don't compare it to the raging blast series, because they focused on the fighting moves, and the playable charcters.
