The first anime that caught my attention so much that it actually made me read the manga... In general I really like fantasy especially with strong female character and here you'll find a whole buch of them ! The story is well developed and intriguing, I have complains only with the ending - it's defferent from the manga which made the continuation of this anime difficult, which is very sad.
Art graphic is very very good. I like how the characters don't look the typical manga humans with large creepy eyes but look quite normal and believable.
Characters are outstanding to me - every heroine has something typical about her and has poles in her personality. Teresa was may be my favourite - in the beginning so cold and heartless and after meeting Clear - she just transformed in a warm and kinder person. I usually don't enjoy only good and only bad characters so I loved the fact that Prissila is not the ultimate evil monster - she also has a gentle side and was thought so much in her childhood it's quite normal how it came out with her...
Claymore is one of the best anime series I've seen. I watched in literally in a night and I'll watch it again and again for sure!
