Adding my amen to the NOs. The main thing that's stayed with me from this movie is the grating look-how-cute-we-are quotes from the plays liberally strewn in the dialogue. Shakespeare in Love has its charms, but is a little too slight to be canonical.
It is possible, however, that it's one of the best of the writer biopic genre. It's hard to think of any that are much good. For example, I just saw the critically praised but mediocre and stilted Dickinson pic, a Quiet Passion, and I'd take SIL over that any day.
