Today was kind of a slog. A few fun or interesting answers, like LIBRARY (37D: Place where many spines are visible) (went in immediately), BIO (43A: Cutting class, for short?) (didn't), and PARIS (12D: "Do not deny to him that you love me" speaker, in literature), but the greater part seemed to be groaners like ORLE (50A: Heraldic border), UNARY (49D: Involving a single element, as a math operation) (whatever you say), and RESAT (47D: Convened anew). I also have a problem with AREOLAE (14D: Eye parts bordering on pupils). The clue hits one definition of the word, so I know it's legit, but it does not Google well at all. Additionally, there is sort of a semantic doubling with CORONAS (40D: Heavenly rings).
On the brighter side, the stacks were fine. BREAKOUTINARASH (60A: Get bad marks?) was probably my favorite. RAISETHETITANIC (55A: 1976 novel featuring adventurer Dirk Pitt) seems a little obscure, but perhaps you knew it right away.
Our difficulty came today at the cross of ETAMINE (33A: Light cotton fabric) (never heard of it) and AMICE (29D: Garment worn partly under an alb) (ditto). Seems unfair, but hey, it's Saturday, so I'm not complaining too much.
Overall it just rubbed me the wrong way. A disgraced college football coach, a potentially lethal, addictive stimulant, abbreviations galore… Didn't love it.
