Spoiler I would have cut the armor in general. Also, cut Viper as well, as her entire character was unneeded. I agree about the Yashida twist, since it quite literally made no sense for him to fake his death (and ultimately made carrying out his entire plan only harder). I would have included the original conflict of the mini-series with Shingen disdaining Wolverine for being a mutant and being unworthy, and on top of Wolverine's hatred of being immortal, added his struggle with his animal vs. being an honroable warrior. In general, making the film more personal as a whole would have been a much better move.
