If you are familiar with Shakespearean comedies, you'll know it's always the same - one or two couples, a lame villain, a bad plan, and a happy ending usually has a wedding. You have all of those here. So, same boring story tweaked by the bard's wit. But, if you are new to his comedies, both the film and the play will be a delight.
The whole movie is in Black and White. If you are not comfortable with it, you have been warned. If that's not an issue, then there's nothing to complain about. This is an excellent adaptation from JossWhedon(Avengers) worth the watch
