There's a very pleasing review of Night of the Necromancer by Jackson Kuhl over at the Black Gate website.
You can read the whole thing for yourself here, but the bits which really shone out for me were as follows:
Over the course of a single night, you explore a wonderfully atmospheric English countryside haunted by things worse than you, a landscape that is half M.R. James and half Ravenloft...
Night of the Necromancer is a new addition to Wizard Books’ reprints of Fighting Fantasy from the ’80s and ’90s, and nearly 30 years of evolution shows in Necromancer’s sophistication.
Gothically fun, cogent, and fat (450 passages instead of the usual 400), Night of the Necromancer is one of the most interactive solo games I’ve experienced this side of a keyboard.
