Unfortunately, Netflix only has the DVD (don't know why the company doesn't stream it, at least during the holiday season), but you can also watch it now via Amazon Instant Video and maybe elsewhere.
An incipient classic in the holiday movie genre, NOEL is for us urbanites who hate the holidays on the surface but secretly pine for connection, redemption and a little real joy. Suffused with sadness and longing (and occasional quirky humor: the winning-the-Xmas-tree scene), the film connects a group of disparate New Yorkers in ways that are humane, sentimental and, in one case, otherworldly.
Catch Noel if you can. It's one of those under-seen and under-sung independents.
