A solid Monday offerring, with a decent theme and some unusual fill.
Let's talk about the theme first. The "bait, cast, bite, reel" sequence makes sense, and the two-word phrases that house them are mostly fine. I'd rather have seen some kind of printing problem clue on COLORCAST (21A: Like most TV shows starting in the 1960s), but I suppose that would only appeal to a very small subset of solvers. The very idea of OSCARBAIT (17A: Film designed to attract Academy Awards consideration), too, is repulsive to me, but I guess it's normal enough.
In the fill we see such lovely things as CHECHNYA (23A: War-torn part of Russia), TOUCANSAM (9D: Avian Froot Loops mascot), DSTUDENTS (32D: Pupils who score in the 60s) (it's a bit unorthodox, but why not? I like it!), and STATESEAL (37D: Louisiana's has a nesting pelican with three chicks). I also quite enjoyed BLACKEYE (58A: Shiner). COACHESUP (5D: Instructs, informally)? Well… ok, I guess that's fine.
The clue for YARD (58D: One of 10 in a series of football downs) seems needlessly complex and, in the end, almost nonsensical. One yard in a series of downs? But I enjoyed the accuracy of the paired, foreign-language "goodbye" clues - 24D: Informal goodbye (CIAO), and 52D: Formal goodbye (ADIEU).
ASS (25A: Ninny) and ASSET (36A: Liability's opposite) looked a little too similar one on top of the other, but overall, a decent Monday.
