Cons:
They suck. They aren't original, they're ususally out of context, and seldom fun to fight. How many helicopters have you actually fought in a MILITARY-THEMED game? 0 that I can recall.
Pointless battles with helicopters is like Big feet to Sora and Kairi. It wouldnt be the same without them. Now you hate them, but without them, youd think, Man, this game needs some helicopters
You bring up a good point, my friend. Sora and Kairi just... need big feet. Who else would there BE to run like idiots in a cutscene? I wish for once, though, just once, that I could pilot the helicopter and blow the bajeebus out of stuff.... eh... it's just a pipe-dream...
