As the others said, there's nothing wrong with enjoying a flawed or even outright terrible piece of media. Everybody has different tastes, different tolerances for issues with what they read or watch, etc; what matters is that you like it, and you definitely shouldn't feel bad about that. The only times liking a flawed show is problematic is if the flaws are a genuinely serious issue IRL (for example, if a major theme of the work is something like 'homosexuality is evil'), or if you go around attacking anyone who doesn't consider the work a perfect piece of art, neither of which apply here.
