If helping the image of aikido is giving a fictional portrait of it, so be it. I'd rater prefer a realistic one.
I would think that any of the well known martial artists-- Bruce Lee, Chuck Norris, and many others would be subject to the same criticism I'm sure. But then that is why it is a Hollywood depiction and not a documentary. If you have seen The Path Beyond Thought, Seagal seemed to be able to walk the walk long before he was up on the silver screen. Perhaps it would have been better for him if he could have lead with that instead of a few of his movies-although Above the Law wasn't bad in my opinion-no wire work that is for sure and Matsuoka sensei's ukemi was pretty sweet.
