Some Trek episodes haven't aged well, it is a 54 year old TV Series after all. So seeing it for the first time without the benefit of nostalgia or lifelong viewing will give someone a much different response to a variety of things. Arena has the potential for humor with the Gorn costume and the VERY slow fight moves. And even I felt Spock's narration of the action was a little much at times. However, I grew up with it, so none of it is amusing to me, but I get why someone new may gaffaw over it. I enjoy Pearl Jam and The Beatles.
