'Killing Mr. Griffin' isn't a remarkable film, and the production values could best be described as "B+." However, it is saved by its willingness to tread into the darker territory of high school peer pressure and cliques with reasonable verisimilitude (unlike, say 'Cruel Intentions' or 'She's All That') and strong performances on the part of the lead cast, especially Amy Jo Johnson as Susan McConnell. Despite her lovely looks and renown for her breakout role as Valley Girl Queen Bee and Pink Power Ranger, Johnson is more than convincing as a socially awkward "Plain Jane" bookworm who nonetheless won't miss a sudden chance to join the cool kids and who tragically casts aside childhood loyalties and moral scruples along the way. The frame story also works wonders to that effect, providing the character introspection that would otherwise have been lost in the screen adaptation.
Nevertheless, the writers seem to have treated the adaptation of the source material a bit hastily in some respects. Mr. Griffin is here portrayed as an anti-social jerk as opposed to the somewhat brash drill sergeant and ultra-strict grader he was in the book, and so it's somewhat more difficult to have empathy with respect to his ill fate. The script also loses texture relative to the novel by its abandonment of the very well-done psychiatric dimension to the character of Mark Kinney (probably due to the difficulty of adapting his or the other characters' backstories in a single-shot film) and its under-exploitation of the Shakespearean parallels in the original plot.
Overall it's reasonably entertaining, certainly better than your average 'Movie of the Week,' and it's definitely a treat if you're a fan of Amy Jo Johnson, but if you've got time to kill consider reading the novel.
