I neither read reviews to have a critic dictate what I watch nor to simply find affirmation for my opinions. I read reviews for insight and for some guidance on what to watch, and/or if I want to see something ASAP. An opinion is only as good as the reasoning backing it up, no matter who it comes from. Good critics deserve respect and serious engagement, but never blind loyalty or bandwagon sentiment. I'm a strong admirer of Roger Ebert and I certainly don't agree with his take on everything.
The thing to remember about parody reviews is that they tend to exaggerate or focus overmuch on flaws or funny details to be entertaining. So, you have to consider what they say in that context unless that person isn't playing their character.
