ANIFORANEYE (62A: Misinterpretation of a biblical code … or the key to answering 18-, 24-, 40- and 50-Across) is in the singular, but all the answers use the plural "eyes." Does it matter? I guess not. But it just seems a tad inelegant. As does starting off the grid with NTH (1A: Ultimate).
Nice little pairing of 44D: Some lose it in their teens (BABYFAT) and 59D: Some get them in their teens (ZITS), but "zits" is an ugly word.
I did unreservedly enjoy the full HUGHLAURIE (3D: "House" star) (coincidentally, we just finished watching "Stephen Fry in America" the other night, and I recommend it highly), and RAZORSHARP (29D: High-definition) (something that Fry and Laurie are, I think, though not as defined here. Except, maybe, if you're talking about costume… but then I still don't know). NEXUS (4A: Link) and NEURON (28A: Cell in a network) are also good.
The theme is fine, and there's some good stuff. OK, how about we say it was fine.
