Gentlemen,
Yes, it all comes down to opinion, but that's the fun of it on a question like this.
For me-
Robert Duvall IS the best Gen. Robert E. Lee in Gds and Generals.
DDLewis was great in LOTM.
Now... not to start a war, or get tarred and feathered.....
I grew up watching Grizzly Adams. That helped to advance my love of history and the period (I started with a bit of a mountain man/cowboy phase and moved to 1840-65). I can't handle Grizzly Adams or Daniel Boone (Parker) any more. I appreciate what they did for the hobby- made it really, but the complete lack of even trying to do it right is tough. HOWEVER! We watch Daniel Boone with my children because the values and morals were great. I explain, 'no, he didn't wear mocassins like that' but I also tell them, 'see, great moral, he kept his word.'
Just my opinion,
David
