Yes, even by the low standards of Lifetime's formulaic, crime dramas, this one is bad. Horrible Fatal Attraction rip-off (and there have been many of those) with no surprises, high school drama club-level acting and a terrible script. Don't let the title fool you--this is tame, TV-14 (I would have rated it PG) level stuff. In fact, it plays like one of those old, Afterschool Movies (don't have sex with your teacher, kids!) with just a bit of racy/violent stuff thrown in. Lifetime has made a few, somewhat-decent time-killers, but this is not one of them. I should have checked the IMDb rating before watching this crud, but it was on Amazon Prime (home of a lot of terrible movies), so I thought "why not." I owe the move one thing along those lines, though: after watching it, I decided not to subscribe to AP after my free trial ends, so Dirty Teacher ended up saving me $10.99 a month.
