Sounds like you haven't played Dragon Ball Z Budokai Tenkaichi 3 (or 2, but 3 is better and has online) on the Wii. Dead serious. Pretty much describes just about everything you mentioned, except the life bars.

The rest of this post is a rant.

If the 3 games you mentioned are the only series you really play, you should take the following into consideration:
-There hasn't been a completly new street fighter since 1997. Of the 3 main Street Fighter games, they actually are quite different and evolutionary. It might seem like the SF series hasn't changed much, because they tend to release the same game at least 2 more times with minor tweaks and makes you buy it again. (Also @vyk, Street Fighter 4 is a 2D fighter with 3D models)
-Mortal Kombat: Grouping that with Tekken and SF seems kind of odd to me. Definitely not in the same league as the rest of the games you mentioned.

If you haven't played a Soul Calibur (any of 'em) or Virtua Fighter (4 at least), you really should sink your teeth into those. Tekken, Soul Calibur and Virtua Fighter are like the 'holy trinity' of 3d fighting games.

As for button-mashing kids, depending on the game you're playing it's your own fault for allowing them to beat you by doing that. I say 'depending on the game' because there are lots of them out there that *don't* have proper anti-newb techniques. In the top fighting games (heck, even in DBZ) there are countermeasures to random button mashing that someone who should be more experienced in the game should be able to exploit.

Really though, everything you described would be more befitting of an action game than a serious fighting game. Particularly the moving camera, in a serious fighting game I feel that should only be limited moves that start with a grab or would otherwise normally prevent the target from being able to react. Using it anywhere else would seriously screw with strategy. That said, if you want action games that are kind of like fighting games (and if you don't have one of the new game systems), check out Devil May Cry 3 for PS2 or Ninja Gaiden on the Xbox.
