This took me more than twice as long as yesterday's puzzle, and it felt like a struggle the whole way! Right away things got off on the wrong foot when I couldn't remember RABBI (1A: Yom Kippur service leader). (By the way, that's a solid C 1A.) Things got better with EDAM (6A: Dutch cheese) and PENN (10A: Talkative half of a magic duo), but it was all fits and starts today.
The theme is one of the common ideas, and it's well-executed, I think. Each of the top four theme answers does what the revealer says it does: BREAKFAST. That is, each one starts with "FA" and ends with "ST." Like FATHERKNOWSBEST (40A: Classic sitcom with kids called Princess, Bud and Kitten). All I could think of when I read that clue was "Married With Children." Hah! Well, I never watched either show, so how was I to know? Also, it's kind of a weird clue for FALSEARREST (52A: Potential charge against a bounty hunter). It took me a while to figure out what they meant.
MARTYR (9D: Thomas Becket, e.g.) is good. IDEEFIXE (5D: Obsession) was surprising on a Tuesday. I like the bluntness of "45A: 20" for SCORE. Let's even go so far to say that's my favorite clue/answer today.
Overall I guess there was a lot I liked in this one, and when that's true on a Tuesday, things are pretty good.
