Or you could look at like this CSI and CSI Miami are the #1 and #3 most popular shows in THE WORLD. That means that it's the most popular format not just in the US but throughout the globe. Shows like NCIS, 24 and Hawaii 5-0 are also incredible popular and no one is commenting on how silly they are. Which seems from your argument is something you'd like.
I'm going to let you off the, "spoofing something that already is stupid argument", cause essentially you are agreeing with me. Spoofs are reserved for poking fun at ridiculous things. Things that are great don't normally get spoofed because they are original and have less common elements that lend itself to parody.
Also your point that the characters are "inept" leads me to believe that you think this is a real show, I'll refer you to google where you can look up spoof and see examples.
I never use my hand as a gun in the show. But then again it's parody.
Seems to me you don't like the concept of Parody or Spoof.
Because based in this discussion, I feel like you have nothing to add and probably have seen the show or are even aware of what parody is.
I'm not arguing that you should like it but I'm rather just trying to show you that you really have no basis to make a judgement. Because it's a general hate of the concept not the specific.
