Mike Leigh Misses with Happy-Go-Lucky

I'm not saying there weren't enjoyable moments (the Tango lesson, the driving teacher) but the rave reviews for Happy Go Lucky seem undeserved for this slight slice of life. Truthfully I had to look up Leigh at IMDB (Ebert, Travers) to make sure that he was, indeed, the writer and director for such pieces of substance as Secrets and Lies (1996) and Vera Drake (2004).
