A lot of people missing the fact this was a huge satire.
The Trogs are how Indians were essentially viewed in that era, just savages and monsters.
"They don't eat blacks because they think they're poisonous"
The whole Brooder character.
The dynamite references and cheesiness that never eventuated.
A crippled man saved the day, crawling into the cave and blowing on some bone
The over the top gore, especially when they killed Nick and he's going on about the "Calvary" coming.
The casting of the girl from Banshee as the Ms O'Dwyer, deliberate misplaced casting, but suits the tone of the movie if you know her Banshee character.
Richard Jenkins.
The script and eccentric character interaction.
This movie is missing comedy in its description, it's clearly a great satire on Indian impressions and Wild West cliches.
I found this movie absolutely hilarious and had some real dark comedy and hidden gems among the dialogue.
Of course all this will go over the top the heads of the average IMDb movie goer who is better of sticking to their Marvel movies with obvious humour and witless one liners.
