La Malédiction de l'île aux chiens

I very much enjoyed Humongous. Yes, it's dark, yes, it's slow, but it's honest. The story is unlikely but plausible. The acting is sufficient to convey the story, and even good by Janet Julian. I immediately contrasted it with Last House on the Left... gritty and plausible, good stuff done by talented amateurs. It is best seen on a TV/monitor with the brightness turned way up.

It is easy to overlook slasher horror of that period due to production quality or unknown performers, but, the early 80s was a boom time with VHS/beta reaching market and semi-professional gear coming to market. With the advances came a greater variety of scripts and interpretation, tho perhaps without the backing of large studios or with less finesse. Don't be so shallow as to overlook them, for they seem to have had quite an influence on the diversity of fringe cinema today.

Give humongous a go if you're a fan of the genre.
