These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Shallow Parody: New York Magazine's review of Comes Out Swinging noted that the show occasionally slips into this, such as getting Santino Fontana's race wrong in the Cinderella parody by claiming he's Latino. The critic noted that it's not a good idea to go shallow when the only people likely to go see a parody of stage musicals are ones who love stage musicals to begin with and are thus more likely to notice when you goof up. The 2014 London edition calling Charlie and the Chocolate Factory a "pale Matildaimitation" isn't much better (Charlie was well into development when Matilda premiered).
Suspiciously Similar Song: Alessandrini has occasionally written ersatz versions of songs he couldn't get permission to parody.
"And although we're a low, Hasty Pudding show, the kiddies cheer on cue... Families come, if they're dumb, but then out they go, when our fuzzy people screw! Don't expect The Muppets, these are horny puppets, rated X on Avenue Q!"
