New syntactical disaster. From Texas:
 
2008  http://www.imdb.com/title/tt1073498/usercomments?filter=love : First of all, if you were suckered or tricked into seeing the 300 (of which Meet the Spartans is heavily based on) and you didn't like it, then Meet the Spartans is totally for you....I was expecting to see a comic book adaptation (of which the 300 was), but wasn't expecting to see all the seriousness.
