I assiduously avoided "Elf" for years. The trailers and clips looked corny and sentimental. Someone on a news show recommended it, so we took a look, thinking to turn it off, but it is surprisingly good, sweet, sardonic, and funny. Re-read "A Christmas Carol." It's a whole new story in the original. Also, unrelated to Christmas, re-read Mary Shelly's "Frankenstein." The movies derive from it, but the novel is a different and much richer experience, a real tragic dramatic depth.
