Welcome back to Film Gutter four our latest skinnydip in the strange waters at the very edge of cinema as we know it. We're far from the safety flags and lifeguards as always, as we dive headfirst into one of the newest films we've reviewed here at Film Gutter, Eat.

Welcome back to Film Gutter, and today the waters are even more murky and horrendous than usual. One of the reasons I wanted to start writing Film Gutter is that I was curious where my line was in terms of offence, shock, controversy and so on. I've always liked things that have been edgy – comedy, TV, film, books – and I set about wondering if I could find a point where I'd say 'you know, really, that's just too much.' When I started this series, I was amazed how many of the supposedly controversial films out there I'd already seen and filed away in my brain as not having made much of an impact on me. Maybe Film Gutter at its heart is a test of my own endurance. 

Butt never has that been more sorely tested than by today's film, Thanatomorphose.

Welcome back to Film Gutter. Today we're still treading water in the deep end as we come to the close of our trilogy of Jorg Buttgereit reviews. After 1993's Schramm, the German director went distinctly quiet on the film front but is now just starting to re-emerge in a small way in the world of European horror cinema. But today's focus is on the sequel to one of the most controversial offerings of the video nasty era – yes, it's time for Nekromantik 2. This movie holds the dubious honour of having copies seized in Munich within a fortnight of its release, a stunning censorship move for the 1990s.

Welcome back to Film Gutter. Let's go for another swim, shall we? 

Today's movie in the spotlight is the second of our three Jog Buttgereit reviews, and the first offering from the director, Nekromantik. Undoubtedly one of the nastiest of the video nasties, the movie is still banned in many countries around the world and was only cleared for screening here in the UK in 2014. I was lucky enough – or perhaps unlucky enough? – to have the pleasure of seeing this movie on the big screen, where its often nauseating imagery was all the more impactful. But what is it that makes this movie so controversial? Well, the clue's in the name – the main subject matter here is necrophilia, which is used as a vehicle to explore the areas of love, sex and death.
