This was a fun one! Frannie started it out, and when I first looked at it she had a good amount of the perimeter done, but in the center - well, the lower center - was the single word "NAIFS." No backup, she just put that right in for 33A: Innocents. Sure, it could have been right, but who puts in a thing like that without crosses? I'll tell you who - someone who's "en fuego." She put in a lot of others without much corroborative evidence, like BAKES for 22A: Sunbathes, informally, and FERMI for 44A: Element #100 is named for him, and they all held up. Ah... except "naifs."
Nice to see Roger EBERT (19A: Late critic featured on the Hollywood Walk of Fame) given a tribute so soon, and MAD Magazine makes it in again (they still have very few, if any, ads). Frannie's favorite (once Naifs fell) was LONER (40D: Company boycotter?), and, of course, any mention of Brent SPINER (38D: Brent of "Star Trek: T.N.G.") is ok with her. My favorites were 15A: Key chain (ARCHIPELAGO), and 1D: Dry mounts? (CAMELS). I know some crossword reviewers don't like the question mark clues, but they are favorites with these two solvers, and there were some good ones today. (40A: Country singers?)
Very few groanable answers. Sure, MANOLETE (29D: Celebrated matador during Franco's reign) and LORELEI (33D: Title maiden in a Heinrich Heine poem) are not, perhaps, household names, but they are interesting, and we had no trouble getting them with crosses.
Overall, another enjoyable Friday.
