2004's THE ALAMO. The best and most historically accurate Alamo movie ever made, but it flopped at the box office and was panned by critics.
I have seen it and enjoyed it. Though, that is the problem with making a film no one wants to see. It fails at the box office, both here and in Mexico.
It might have done better or maybe not, if the violence had been more violent. Originally, the violence was suppose to push the film into a R-rating, but later it was toned down to get the rating it did.
The failure might also have been due to the fact, that, as far as I know, it is one of the few films or the only film to show Davy Crockett being captured alive, then executed. 182 years after the battle, historians still go around and around as to whether Crockett was killed before or after he surrendered.
And while most critics panned it, Roger Ebert liked it, giving it a 3 star rating, which is not great, but good, better than average.
