better than black and white by far.
Good stuff: Epic pokemon with nice moves and battling two groups at once (aqua and magmar) as well as 3 legendarys (not including latios and latias) and a nice movie towards the end of the game. Can be good or bad but it's the same battle system is the same as always and has graphics that are adequate (not fully 3D but not a mediocre 2D either). Also being able to trade between the fire-red and leaf green versions is awesome aswell.
Bad stuff: If your sick of pokemon then this game you WILL find boring and repetitive same gym hunting as the last and newer games. not very different from ruby and sapphire apart from the legendarys you catch and the teams you face, may want to reconsider buying if you own 1 of the 2. Also the game in itself like most pokemon games is easy all i do is train up my starter to beat the elite 4 not really much need to "catch them all" :P
in short a great time killer and game if your a long term fan :).
