Cinemania has my review of The Scar Crow. It was pretty much the guide for how not to make a low-budget horror movie.
I felt like it was aiming for a sort of Severance meets The Wicker Man vibe (High Weirdness interspersed with witty sarcastic English people getting humorously murdered) but ended up flailing wildly back and forth between Troma-flavoured gore madness and the dullest possible kitchen sink melodrama.
All the synopses I read of this movie talk about the witch panics in early modern Europe (an interesting period of history and good for the High Weirdness angle). Unfortunately, The Scar Crow doesn't really dig into the material that deeply, and undercuts any point about the accused women being wronged by having its witches actually be wicked witches who truck with the devil and summon the dead.
Actually, the basic setup reminded me a lot of another terrible movie - Lesbian Vampire Killers* except that LVK was over the top and campy and actually bothered to flesh out its ludicrous back story. It also had the balls to pitch an imaginary sequel about gay werewolves post-credits.
Troma-gore can be pretty good if that's your thing (and the two Troma-y scenes in The Scar Crow are pretty hilarious**) but you have to wade through a lot of unlikeable men discussing their uninteresting relationship dramas to get there. Also montages - exercising montages, studying magic montages, burying a corpse over and over again montages, drinking montages, drunken making out montages, endless, endless, dull, dull montages.
On the plus side, this movie and The Mark of the Beast have taught me a valuable lesson - if the opening credits of a movie are just text over moving water and water is in no way relevant to the content of the film, it's probably going to suck.
* Disappointingly, just a movie about killing lesbian vampires - not (as you might have hoped) a movie about how lesbianism magically confers some sort of anti-vampire powers.
** Putting this down here so I can add a pretty pointless potential SPOILER WARNING... The first guy to get killed by budget-Jeepers-Creepers is killed by having his (obviously fake hot-pink plastic) cock ripped off in the cheapest-looking manner possible, complete with amateurish blood spatter from the "wound".
