Well for all the history nuts who have seen it, is it as glaringly inaccurate as Gladiator was? FYI I liked Gladiator but it still was pretty damn off in terms of historical accuracy. I learned about most of the inaccuracies after I saw the movie, and thus they really did not distract me from enjoying the film on the 1st viewing, but after I learned about them, they did distract me in my later viewings of the film.
I neither like or dislike Tom Cruise. So I won't go to see or avoid a movie on the merit that he is in it. I have liked a few films he has made. Top Gun, Risky Business, and Minority Report. If I have seen any others than I really don't remember them, and that goes to show you how much I liked them.
There is only one actor I despise enough to utterly avoid all the movies that person has been in (hint, it is another of the prettyboys of Hollywood.)
Though I will say this. Tom Cruise you ain't no Kenshin and you never will be
