I didn't enjoy this one all that much. This probably has something to do with the fact that I didn't see the fish-name gimmick until after I was done, so for most of the solve, I had this dragging "so what?" feeling. You figure out the deal with the theme answers themselves very early, with FISH / HOOK giving it all away at the top of the grid there. Since I got FISH / HOOK very easily, I figured, well, the answers hook, that's what the circled squares represent, ta da, the end. I didn't really top to think "wait, why *these* answers?" until I was finished, and finishing mostly meant dealing with a ton of overfamiliar short stuff (SSNS and AROD and INSTA ESTES ASADA KEA SNL etc. and somehow QUA *and* ERAT?), or short stuff with deliberately toughened clues, like the clues on ORR, say (28A: Mary whose short story "The Wisdom of Eve" was the basis for 1950's "All About Eve"), or LABOR (25A: Accouchement)—I figured "Accouchement" had something to do with sleep ... but then it was LABOR, and I was like "huh, that's work, work's not sleep," and *then* (when I finally looked it up) I was like "ohhhh ... thatLABOR"). I liked DIASPORA (5D: Group migration), and the theme answers themselves are pretty colorful, but there was just too much 3-4-5 stuff for me to get much of a joyful rhythm going, and it's hard to get terribly excited about something like INK STANDS. I see now that the FISH / HOOK theme has its two layers, and I think it's reasonably clever. But the actual solve was kind of plodding and by-the-numbers. 

• CAT PEOPLE (23A: Ailurophiles) — "CAT PEOPLE" is a classic Val Lewton horror movie; you can clue CAT LOVERS as [Ailurophiles], but you cannot pass up a Val Lewton horror movie title when you have your shot at one, because, I mean, when is "I WALKED WITH A ZOMBIE" ever going to appear in a grid, realistically? Also, clue VAL as Val Lewton. Also, LEWTON, VALLEWTON, all VALid answers. 
• TSAR (56A: Historical lead-in to -evna or -evich) — I had IVAN :(
• MALLORCA (7D: One of las Islas Baleares)— the biggest of the Balearic Islands, which are spelled "las Islas Baleares" here because the answer has the Spanish spelling of the island (two L's) and not the English (a J)
• LISPS (25D: "Frontal" or "lateral" speaking features — well at least the puzzle isn't mocking speech disorders today, as it so often has
• KALE (48D: Trendy ingredient in a healthy smoothie) — stop treating KALE like it's some hipster fad. The "trendy" bit here is *$%&ing annoying and completely embarrassing. [Ingredient in a healthy smoothie]—you see how that works just fine, right? KALE is a really healthy leafy green vegetable and it's everywhere, in all kinds of things, all the time. Eat it, don't eat it, whatever, but this weird thing where people treat a simple green leaf like a "lifestyle choice" is beyond me.
