Pokemon The Movie Black/White—Victini and Reshiram/Zekrom

I haven't watched this movie/these movies, I got them with the intent to, but I never got around to it. Very interesting concept to have two different movies but it's the same movie. Fits in with the theming of the games, but I'm not sure if it's like, worth it to watch both, or if theyre just the same movie with some differences. It feels weird, but I am intrigued. It's also why I haven't watched it yet, because I would need to watch them both I feel. Right?
