Ok. This one is often described as one of the worst ever. I'm going to defend it somewhat. This one was made in fun like "The Romans" and should not be taken too seriously, so just sit back and enjoy. Don't worry about Steven and Dodo's clothes, the accents, the singing, the historical inaccuracies, and such. I know that "The Ballad of the Last Chance Saloon" can get a bit old, but it tells the story like a lot of old Western films did and fits perfectly in this vibe. Everyone making this serial seems to be having fun, so we should too. Even the Doctor gets in on the fun by calling Wyatt Earp "Mr. Werp" throughout the entire story!
I actually really enjoy this one.
