I absolutely promise that I had planned to watch something sensible this week. At least, as sensible as a Christmas film is ever likely to get. Then I discovered that Netflix had released a film called I Believe in Santa about a grown man who still believes in Father Christmas. How could I not watch that? It sounded so stupid. Even more ridiculous than any of their previous festive offerings. Could this possibly be a new low for the streaming service or would it end up being the best thing they’d ever done? I suspected it would be the former but I had to find out for myself.
