Peter Griffin [SEP] Criticism and controversy
Peter has been criticized for being too similar to Homer Simpson. Peter has appeared in some episodes of "The Simpsons", in these episodes which he has been featured he has been depicted as Homer Simpson's clone or is accused of plagiarism. Ken Tucker of "Entertainment Weekly" wrote that Peter is Homer Simpson "as conceived by a singularly sophomoric mind that lacks any reference point beyond other TV shows". Robin Pierson from "The TV Critic" criticized the Griffin family for being too similar to the Simpson family; and he said that Peter "has Homer Simpson written all over him". This is eventually made fun of in the episode "Ratings Guy" when, after Peter ruins television and goes to the networks to reverse the changes, Homer Simpson shows up with the same plight, with Peter going "A-ha! Looks like this is one WE beat YOU to!" In "The Simpsons Guy", a crossover episode between "Family Guy" and "The Simpsons", the Griffins end up in the town of Springfield after their car is stolen, where they meet and befriend the Simpsons.
