I've heard many people rave about how great the battles are in Deep Space 9, but when I watched it, I found them rather boring and formulaic. Nearly all the Federation ships get destroyed in the first few seconds of the battle while the enemy goes practically untouched, then the heroes find some weakness to exploit that destroys most of the enemy in only a few shots. *Yawn*
The battles in Babylon 5? Now that was some real edge of the seat action that holds true no matter how many times I watch it.
