True, and that means they are exponentially ahead of most movies from the past. Shall we consider the '92 Winchesters the cavalry carried in "They Died With Their Boots On"?!
Yep, most westerns back then were on a low budget and 92's fired 5 in 1's quite nice. Today more of the ones who watch western movies do know a bit of history, was always that way.
To be truthful a true historicaly correct movie would be boring.
Look at the two movies made about the same subject made in 93 and 94. We all know which one most like best, despite that the other one is more accurate.
And that is even among those who should know better.
To be truthful we're lucky Rough Riders got as much budget as it did, it sure could have been far worse.
