Not sure what to say about it. One thing that popped out at me is the use of the play within a play which seems to come up frequently in Shakespeare's work. I don't really know what to make of it.
I think I liked this one less than Twelfth Night for a couple of reasons. First, I didn't have much enthusiasm for the mix up of the couples, whereas in TN I had some definite anticipation particularly around Malvolio. I also thought the dilemma of the multiple levels of identities in TN was more interesting and so there was more tension for me and I had more sense of something happening in TN.
I suspect that I prefer the histories and the tragedies to the comedies. I think to a certain extent I can appreciate the word play and the absurdity of a queen falling in love with an ass-headed working man, but I tend to feel less engaged than I have with some of his other plays.
