First off, this OVA series is very different than the TV series. It's much more serious, bloody, poetic, and the art is very different. Don't expect to see any of Kenshin's silliness and "oro!" remarks here. Don't worry--you still have the voice actors from the TV series in Japanese.
Since there have already been plot reviews, I'm not going to go over that again. In my opinion, I found the plot for all 3 OVAs to be brilliant.
In Trust and Betrayal, you get to find out more about Kenshin's past as a Hitokiri and how he got his cross-chaped scar. These 2 OVAs were my favorite. The music was breathtaking and wonderful, as was the animation, although I preferred the TV series' style. There's also a lot of symbolism going on--the crosses in the graveyard and Kenshin's scar, the white plum, etc. The sheer beauty of these OVAs can also be seen in several scenes such as the part in Trust where Kenshin is attacked by an assassin as Tomoe is walking down the street. That whole sequence with the "bloody rain" is silently powerful and very memorable. The ending of Betrayal was very moving as well as Kenshin is out helping in battles while the wonderful music score is playing in the background.
Reflection takes the viewer 15 years after the TV series. All the characters have obviously aged, especially Kenshin. This OVA consists of many flashbacks to the events in the TV series. For those of you who haven't seen the TV series, some of these flashbacks may not make too much sense. If you're familiar with the happy, funny Kenshin from the manga or TV series, you'll be surprised at this. The characters, although they have matured, seem to have undergone extreme personality reconditioning. For some viewers, it might be horrible to see the characters like this. Kenshin is all depressed and guilty, and he's also rather selfish in a way. While doing the generous act of helping the world, Kenshin is simultaneously selfishly leaving Kaoru to wait for him to return home. Sanosuke, who is supposed to always be with Kenshin, lets Kenshin leave on the ship alone in his weak state. The real Sano wouldn't do that. With that aside, Reflection is a very moving conclusion to Samurai X that brought me to tears several times. The scene where Sano tosses the fish to Kenshin was an especially memorable scene that shows just how much Kenshin has aged from being a strong swordsman to his present state. The saddest part was the end, of course. The way that it was set up, plus the amazing music, help make it even more powerful.
Now that I'm done rambling about why I like the OVAs, I'll point out a couple of things I didn't like:
-The English dub wasn't too good. PLEASE watch it in Japanese with subtitles!
-There's a couple scenes where "real life" shots were put in. (Real water, real trees, real fire, etc) They were a little awkward and made me chuckle.
-Kenshin doesn't really use breathtaking sword techniques. You just see him slashing a lot.
-The extras and special features weren't all that special
And I'll sum up the good parts:
-One of the BEST musical scores I have heard in my life--ranging from exciting percussion rythmns to sad, moving, and beautiful pieces. (There are 2 scores to this--one for Trust and Betrayal, and another for Reflection)
-Action!
-Beautiful--art, story, the way it was told.
Yeah, that's about it. I think that any Kenshin fan should give these OVAs a try after watching the TV series. If you can't seem to keep your attention in movies or anime, you might want to skip this one. It's not one of those edge-of-your-seat presentations. This movie really makes you think. Oh, and younger people shouldn't see this. Trust is a little gory, the OVAs in general might be too hard to understand, and all the poetic beauty and symbolism might be overlooked.
