There's an anime festival in my country right now (
http://www.animefest.eu/JAFF7/kava.php?&lang=en). Among other movies, they're also showing all three Berserk movies. 5 EUR per movie, which is an okay enough price. They also played the 1st movie last year, which I watched then, and I watched the 2nd and 3rd one this year.
Honestly, while the movies are somewhat missing what made the manga so damn unforgettable - its strong psychological and philosophical overtones - I thoroughly enjoyed all three movies. I'm of the opinion that the movies work well as a sort of supplementary material to the manga, which contains the story in its full glory. Sure enough, there's some parts where the CGI looks awkward and clunky, but overall, I was impressed with the visuals - the 100 man battle in Pt. 2 and the fight with Silat in Pt. 3 were awesome, IMO.
I liked the music as well. Like many Berserk fans, I'd appreciate an OST fully made by Hirasawa most, but Sagisu did impressively enough. Pt. 1 had some very captivating orchestral songs (Des Liens Solides and Avant La Tempete in particular) and parts of the music of Pt. 3 are somewhat reminiscent of Hirasawa's stuff (especially Bruit de Pierre) although there's lots of quite different stuff as well. My friend who I went to watch Pt. 3 with (a fellow Berserk fan) HATED the song that it had during the climax (literally) of the Eclipse (Sonate pour piano nš 23, can be heard here:
http://www.youtube.com/watch?v=5DuoUYwiJms ), she thought it was too involving and interactive and didn't let one get into the scene, but I think it worked really well. Oh well, I guess there's bound to be strong opinions about that.
There were some omissions that were a let down for me. Particularly (1) the Bonfire of Dreams, (2) Casca's memories about the case of Griffith and Gennon and (3) Zodd's short appearance during the Doldrey battle, which would've fit into Pt. 2. (Would've been fkn awesome to have Wyald in Pt. 3 also, but properly putting that in there would need a minimum of half an hour, so I'm okay with them leaving that out.) Oh, and the voice acting of all three main characters (Guts, Griffith, Casca) was better in the '97 series, I think..
But I'm on the whole pleased about how they dealt with stuff that did make it into the movies. Three exceptions: (1) Zodd's scene in Pt. 1, which lacked the horror effect it had in the manga and the '97 anime, (2) Corkus having a strong comic relief character vibe and (3) the goddamn dance scene in Pt. 2.

Other than that, I don't recollect anything that I'd rather they would'nt've put in the movies.
Looking forward to further installments, anyway.
