I really wanted to like “The Prince” — but we already have “Family Guy,” so…The new animated series on HBO Max comes from Gary Janetti, who has a long history with “Family Guy” as a writer/producer. He brings that skewed sensibility to “The Prince,” but not as cleverly, and since it’s streaming — and not on network television — he gives his caricatures (including Queen Elizabeth) free rein to spew profanity and drop F-bombs like nobody’s business.
