The trailer of the new movie “Linoleum” might have viewers thinking it’s about a nice, schlubby family man going through a midlife crisis, with elements of teenage romance and sci-fi added in not just for contrast and verve, but to court a wider audience. They wouldn’t be wrong exactly, as the movie does appeal to the fan base of entertainments like “Stranger Things” while remaining focused on the foolhardy activities of its main protagonist.
