I stopped reading the thread around page 2, but I'll throw in my opinion.

I didn't think it was great. The fights were amazing. I mean really, really amazing. The rest was horrendous.

I felt like the only reason I knew a scene was meant to be dramatic was because they had dramatic music playing in the background. It was actually (literally) laughable. As I laughed out loud several times during the beginning of the film as I realised that if nothing was happening, it would be slowed down to make it look 'interesting'.

The characters themselves were awful. There was more or less no tangible relationship between the King and Queen. One (funny, inappropriate and entirely pointless) sex scene was not enough to sell it as a relationship. The repeated ranting about 'freedom' was ridiculous. Spartan society was barely shown, let alone shown to be free. Why the hell was I supposed to care if it was protected? Also, the fact that the Spartans were killing slaves (as in people who had their freedom taken away) sort of entirely undermined their apparent heroism.

The rulers of Sparta were corrupt, the ideals the 300 fought for laughable, the style of any non-violent scene (save for the apple eating) was dull or pretentious, and the characters were almost all dislikable or stupid. Basically, fight scenes awesome, everything else, terrible.
