Re: What direction would you have liked the third act to go in?
-Reveal Yashida's identity as the Silver Samurai earlier, right after Viper talked to Wolverine at the lab.
-Yashida asks for Wolverine's healing factor and as exchange, Mariko will be cured from the poison that Viper injected into Mariko's body
-Then when Silver Samurai is about to chop Wolverine's claws. Yukio shows up and deactivates the electricity.
-Longer fight scenes with Yukio/Viper.
-Mariko will not being throwing claws at Yashida (that came across not well in the official version)
-A final battle between Wolverine/Silver Samurai in a Zen garden (at the top of the temple) would be sweet! So Kill-bill!
-No random outfit change for Viper.
About Harada, let Wolverine beat him during the ninja fight sequence.
