The first time i watched 300 i was blown away - exciting storytelling in a cgi pronounced world. Second and third visits leave me missing some of the excitement as its flaws are revealed.
The acting is poor, storyline not historically accurate and the overuse of cgi becomes too much. However that may be expected for an action film like this and you get what you expected.
On blu-ray the film makers vision is shown in its glory. Lots of grain to project the comic book look he wanted. This does not lend well to a HD release and to me spoils the party. You will not be showing this film to your friends to showcase your blu-ray set-up.
For me the film is a 4 but is knocked back to a 3 because of the HD release not being to my liking.
