A fun theme today. I love it when the revealer, or a clue, for that matter, is just so blatant. I think the first one I got was NEMONAUTILUS (10D: Example from sci-fi literature), but that's only because I tried "blacK" for SAJAK (1A: White's partner), and didn't realize that that was a bit too blatant until maybe JIGS (3D: Lively dances) and ATE (4D: Polished off) (they just love this kind of clue!) went in, and then those other two captains and ships came very quickly: AHABPEQUOD (2D: Example from classic American literature) and KIRKENTERPRISE (5D: Example from television).
My favorites might have been CRUNCHGUPPY (63D: Example from advertising) and LINCOLNUSA (75D: Metaphorical example from poetry). Those are very nice.
Least favorite clue: 102A: Helpful household pets (RATTERS). Yuck, just yuck. Where these are helpful, a household should not exist.
Overall, the fill felt like a mixed bag. Some lovely, some strained. I know that this is very often the case, but as I was solving, I felt this tipped a bit toward the "strained" side. ONAGER, CENTIMO, BIOTA, and lots of abbreviations. It played hard for me, maybe that's all it was. I mean, the theme was good, and it seemed to be adequately dense... let's call it a wash.
