I particularly liked the interview with the guy who scripted and directs the "re-creation" of the gunfight. I had heard (never seen personally tho) that the previous crews doing the re-enactment were hardly appropriate. I had heard of a 300# Doc Holiday and the referenced long white haired Wyatt Earp.
Glad they changed that. Also a nice touch to humanize the McLaury's and Clantons a bit, even though they (IMHO) were on the wrong side. History needs to be fully fleshed out, but not Doc Holliday.
