To be fair, Bowser did have a few new tricks up his sleve for each battle, but yeah, they're pretty much the same. As others have said, this is in keeping with the Mario tradition - even SMW had repeated boss battles, as did SM64, but I admit I was dissapointed by the final battle. Of course, the entire ending was weird - I dunno what happened there - so I guess it's in keeping with the rest of what's going on.
