Honestly, this movie, with its colorful low-budget aesthetic, love of monsters, and weird combination of B-movie horror tropes, should have been much more fun than it is. Vesely takes the concept of "What if the "Thriller" music video actually was a full-blown B-movie?" and really runs with it, but something just doesn't stick. The main problem with Slice, other than the many jokes that don't land, is how needlessly complicated the plot is. There's a drug lord named Big Cheese, a witch coven, a ghost gulag, prejudice against said ghosts, prejudice against supernatural beings in general, a portal to hell, and a murder mystery to loosely tie all these things together. It's a lot to cram into an 83-minute horror-comedy with an '80s-pastiche aesthetic that begs for a cult VHS release ten or fifteen years from now. It becomes work to watch -- I found my eyes sliding over to the Wikipedia summary a couple of times just so I could keep up with the plot.
What should be the most fun aspect of the movie is that it's clearly made by a director of music videos that have a certain flair. "Angels" involves Chance scooting through the sky wearing a pair of animated goggles, and "Sunday Candy" was filmed on a stage in seemingly one take with rolling sets made of wood and painted to look like locations from a school play. There are smoke machines and neon lights all over Slice, and the ghosts are simply actors with their faces done up with Halloween store paint and dark eye circles -- which is actually a pretty funny bit. There's a low-budget style to the movie that I respect, that's all the more jarring when the finale gets to the special effects light show. While Vesely clearly has an eye for style, he fails to back it up with a story that's as fun to dive into as its, frankly, dope opening credits promise it to be.
