SEASON PREMIERE: Not a recommendation, just an observation. This is the final season of this sitcom, which has gone on much longer than anyone involved in it dared dream – especially after the controversial departure of Charlie Sheen. Jon Cryer’s co-star, ever since, has been Ashton Kutcher, but this season will be the last lap around the track for both of them. So it’s time to pull out the Halloween costumes – a zombie Elvis for Kutcher, and, for Cryer, a costume that’s just Ducky.
