I recently saw 300. Here’s a quick description from the site:
“Based on the epic graphic novel by Frank Miller, “300” is a ferocious retelling of the ancient Battle of Thermopylae in which King Leonidas (Gerard Butler) and 300 Spartans fought to the death against Xerxes and his massive Persian army”
I had fairly high hopes for this film, not so much for the story, but for the visuals. It has a very stylized look to it. In addition to the many computer generated backgrounds, the entire film has a look similar to HDR (High Dynamic Range) photography, and is overly saturated.
Although the film does look awesome, I found it to be only moderately entertaining. I don’t think it was really worth 2 hours in the theater. I personally think that everything you need to see is in the trailers.
I wouldn’t actively discourage someone from seeing 300, but I would caution them to go in with reasonable expectations.
