I caught the second half of this on TV and it took me by surprise.
The film was probably pulled out of my "never gonna watch" list, but it's quite a good action movie! The characters are well thought-through and believable, the CGI and costumes, however cheap, bring a lot of fun and the director surely knew what he was doing.
The siege scene is way more engaging than Lord Of The Rings one. Also, TROLL IN THE DUNGEON!!
