Buffy the bug-hunter.
14 June 2015 | by (Hampshire, England) – See all my reviews

When Buffy's biology teacher Dr. Gregory (William Monaghan) goes missing (only to turn up later minus his noggin), sexy substitute teacher Natalie French (Musetta Vander) takes over his classes, much to the delight of the male pupils who are only too happy to help out with the class project. What they don't realise—until it's too late, that is—is that Miss French is actually a shape-shifting she-mantis, a giant cannibalistic insect looking for virgins to fertilise her eggs, after which she devours their heads!

As a fan of cheesy science fiction films, particularly those featuring giant man-eating bugs, I think I enjoyed this one a little more than your average Buffy fan. The episode starts off in fine form with Xander fantasising about Buffy, impressing the girl with both his vampire killing and fret-widdling skills, but he soon forgets about the slayer once Miss French starts to release her pheromones. Xander is lured to the home of his new teacher, who is waiting for him in a cleavage enhancing dress, clutching a pair of Martinis; his dream of scoring with an older lady turns into a nightmare, however, when he wakes up in a cage in the basement, with Miss French now in mantis form, preparing to lay her eggs.

Xander's awkwardness with women provides some genuinely funny moments, and Musetta Vander is a nice distraction, but for me this episode is a winner thanks to the terrific mantis monster at the end, a cool animatronic creation that reminds me just how much I prefer practical creature effects over CGI.

7.5 out of 10, rounded up to 8 for IMDb.
