I may be in the minority, but, I found 300 to be a fascinating film, from a technical standpoint alone it's worth seeing at least once. I also didn't find it to be severely homophobic as some others did. 300 doesn't try to be anything other than a graphic novel brought to the screen.
Exactly my thought. As a graphic novel put on screen, I thought it was fantastic. I also found parts of it enormously moving and the effects work was sometimes quite remarkable (I didn't think the CGI animals were great).
My only real complaint was that the battle stuff went on too long for my tastes. The first battles where the army acts as one were stirring. Later, when things get desperate and it's every man for himself, then it became repetitive, and I got antsy watching it.
And, on a purely personal note, there was quite a bit of eye candy there that I wouldn't have wanted to miss.
