I like Higher Universe. They do a good job and I hope they continue to create new things with the same enthusiasm. That being said, I can't really recommend this movie to anyone.
It's like a friend asking you to watch their home made movie. I can enjoy the movie because I can see how my friend enjoyed making the movie, but how am I supposed to recommend that to anyone who doesn't know my friend? Production quality wise Grotesque is fine. Very watchable by no-budget indie standards. But when everything is done well, nothing really stands out.
The big sales pitch is the gore, but the vast majority of it is people being sliced by knives. Not that that in itself is a problem, there's just no catharsis. Things just happen like checking off items on a list. Even Mildred doesn't really have a character journey. She's not really loveable, she's happily spiteful and murders people at whim. Which, again, is fine, but it's a trait that turns on and off in a deus ex machina like manner.
Compare it to Hot Box, another Higher Universe film that features Elizabeth Chamberlain as Mary, a religious conservative that goes to a house party in effort to convert its party goers. Mary has a goal to convert people, but the story shows that she has a personality which is attracted to the party activities and she struggles to achieve her goal. By the end of the story her character has changed and developed because of her experiences. It's a notable story in a movie that has lots of memorable developing moments amongst its many characters.
Mildred could have her own developing story, but it wasn't built in. Mildred is sad because of her nose. Mildred loses her nose and kills people and this makes her happy. She eventually gets a boyfriend. That's about all we got. Mildred's direct antagonist, her superior at work, is more memorable because she has material goals and personality impulses guiding them. The real story of the movie is essentially the two or three scenes where her and Mildred directly interact.
I've harped on long enough. Grotesque is a nice indie film that was made by talented, fun loving people. It invites the audience to watch the fun, but it misses the mark on actually involving the audience to partake in the fun.
