My absolute main gripe with this film was that they left out, what I felt, were some important scenes from the manga. There are more and the first one isn't that important but I like Judeau so I included it.
- Judeau having the fairy dust in order for Gatts to be able to fight in the Battle for Doldrey.
- The scene with Gatts and Caska overlooking the Hawk camp, where Gatts first brings up his plan to leave the Hawks.
- The entire assassination scene at the ceremony where the Hawks and promoted to 'White'.
- Zodd throwing his sword to Gatts in order for him to kill Boscone.
There were some positives to the changes the made though, in particular the Charlotte and Griffith scene. I thought they showed Griffith's behavior and mental state deteriorating quite well, between his showing up in the middle of the night, his mind being on Gatts rather than the princess while they were having sex, to the fact that he was crying after the sex was over. And despite what I felt were unnecessary changes to the 'Hudred Man Slayer' scene, it was still very well done.
Now with all that said they're still doing a good job with the series and I hope they continue on past the Eclipse. I've always wanted to see the fight on the Hill of Swords animated.
