It didn't come into play while solving, but we really like the word loop theme in this one, now that we see it. It's elegant, really, as it runs around the perimeter, and the fill, with one or two exceptions (RUPIAH (54A: Indonesian currency) and ADRIP (69A: Leaking, as a faucet) (yuck)), isn't badly strained. It's not terribly inspired, mind you, but it's not terrible, and, like I said, the theme is really kind of cool.
I had no idea that one of the pigs in Animal Farm was modelled on LENIN (45A: Inspiration for Old Major of "Animal Farm"). Interesting. It seems I missed a lot of the specific subtexts in that book, actually. I mostly remember the old horse, Boxer. Poor guy… and speaking of fictional characters, it's cool that WILEE (1D: ____ Coyote (toon)) gets into a grid, but it would have been much cooler if he were fully in there, instead of just partially so.
CORD (13D: Telephone attachment) will soon be obsolete, if it's not already (although, I answered a corded telephone while writing this review!).
Actually, the more I look at this, the more junk I see (AWEE, OBER, ISE, LETA, ORME), but there are also some nice downs. SVELTE (27D: Gracefully thin), SEXUAL (49D: ____ relations), NEUTRAL (46D: Car gear). The clues aren't much, but hey, it's Tuesday.
So, let's call it a wash. Decent theme, less than perfect fill.
p.s. I learned from the Crossword Fiend blog that the Os used in the word loop (as the only vowel) are absent from the rest of the puzzle. OK, that will strain the fill a little, so I guess we have to be even more forgiving of the junk. But at what point does the sacrifice of fill at the expense of a trick become too much to bear?
