Well he fights a few before Ras, not a SLEW. Not realy that much to show his true skill. Even Still there is an obstacle that really does'nt make the last battle anything to remember, in terms of physical battles.
Yes in Costume. But He fights Ras about twice, and previously they seem to spar, and once with some type of weapon, and one time without. Eventhough there seems like a lot of battles, trust me, it's not really that endulging at all. And they seem to be below Bruce's porwess and most importantly INTELLECT. Even in his first year, even before he becomes the bat, right after his training, he's more accomplished, and smarter then GOyer makes him in this script.
And for your last question, here's what I mean. It's stale. Unless while shooting they totally rework the scenes compared to how it's written, the fights in here show signs of improving upon the previous movies, but in this category the previous movies TOTALLY sucked when it came to combat, so this script to me really is'nt trying hard enough.
Case in point, look how good the fight scenes in Blade 2 turned out,...Same writer. Batman Begins cannot even slightly touch Blade 2 in terms of the fight scenes alone.
The best scenes seem to be at the beggining, BUT, honestly this just seems like they are making a whole bunch of NEW mistakes!
And did you see the costume...it's STILL a RUBBER bomb shell, this is totally stupid, as no one can really fight in something made like that. Im really dissapointed with the WB once again.
