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.
Magnificent Bastard: Farley Flavors. In the end he doesn't get Janet, but he gets the good guys tossed out of the taping and proceeds to successfully turn his charms on the ambitious Macy and save the show, and it's safe to assume his media empire will continue to grow.
There's actually quite a few who do like Jessica. While Susan was the perfect Janet for Rocky and has a sweet voice, Jessica is a far better singer and a solid actress in her own right. Listen to her solo "Old Souls" in the amazing Phantom of the Paradise. Her voice is absolutely beautiful in its unusual depth. Those who don't like her tend to be those who don't like Shocky - for the same reason. They expect it to be the same as Rocky.
Jessica has quite a lot of fans in the Rocky community, for both Shocky and Phantom - especially now that she did a Barry Bostwick-esque turn, and has learned to embrace her RHPS fan base rather than shun it.
