As other reviewers have noted, there are glaring plot problems with this episode... but I still loved it. Tom Lynott is a flawed character, but with enough good and bad qualities to be very real, and his portrayal of a wild west adrenaline junkie was great. I thought the bad guys were a hoot, and, as someone else mentioned, a who's who of Gunsmoke alumni.
The dialogue cracked me up; it's as if the writers tried to cram in every (supposed) old west saying they could think of! Some that I can remember:
I'll tackle ya flatter than a bug's pockets.
Pack 'em into the jail tighter than a long fish
in a short can.
Close your mouth before the bees hive.
All right, drop your knife, or I'll air out your bread basket.
All in all, a very enjoyable episode!
