This is the first puzzle I can recall doing by this author, and I'd like to say I enjoyed it, but that would be lying. It has the maximum number of answers in a themed puzzle, at 78, which means an awful lot of 3-letter answers. And it skews old-fashioned. We get James AGEE, 2001: A Space Odyssey's HAL, Peter GUNN, Cocoon's Don AMECHE, and Gomez' TISH. One of these might have been fine, but five feels tired. Not to mention ancient crosswordese ETUI, IOTA, and SETTO.
A couple of things that work well are the two nine-letter answers at 3D and 36D, matching up so cleverly: THESCREAM and PSYCHOTIC. I also very much enjoyed the side by side 40D: "Don't count on me" (NOTI) and 41D: "You can count on me" (IMIN).
The theme works well enough, especially with five answers. My favorite is CRADLETOGRAVE, with SEATOSHININGSEA coming in second for the silliness of the clue: All, for an anthem writer. As if your standard anthem writer would typically use that phrase. That's cute.
The rest I can do without.
