The only reason this episode is worth watching is its historical value and brief peace theme. As you may have read in the summary, this is Elmer's debut. However, in this he is not yet quite Elmer Fudd. Elmer Fudd evolved from a character called Egghead and that is what this Elmer Fudd resembles.
The other good points of this episode are the animation, which is well done and the fact that Elmer Fudd is a "beautiful" peacemaker.* There is virtually nothing else about this short that makes it worthwhile, unless you like to see cowboys constantly shooting each other for no reason. There was one "joke" that I found very sad, when a chicken looks proudly at her eggs and then they are shot, "Three days hard work, all shot to pieces", or something like that.
I recommend this episode to anyone who likes to see unnecessary violence, or an Elmer Fudd pleading for peace. I hope you enjoy this more than I did.
*When I say beautiful, I mean he does not look beautiful, but the way he pleads for peace is beautiful. I do not blame you if you do not understand, I have a very odd way of perceiving things. :-)
