Well, after not having watched this movie in about 20 years, I finally did again. The original story has always been my favorite by far. I read it first time when I was 7 years old, and have read and watched just about every adaptation since. While this thing takes some artistic liberties, when it comes to the plot and story, it works very well. It's not however flawless. While I'm a huge Caine fan, this is one of the times where he's overdoing it, big time! Besides that, the addition to the plot, actually makes the characters rather 2D, it lacks character development, even when it comes to Hyde. There's very little info about Jekyll's experiments and research, which is also a shame. It's very worth watching, but don't expect a classic masterpiece like the '1931 adaptation. It is however way better than any of the other adaptations, especially to two horrendous 2006 and 1941 adaptations.
