Couch Potato is brought to you today by the letters DVD and the colour blue. I love the Muppets, I really do. Unfortunately there are more than a few (of the non-animated variety) in our potato sack today. This week sees a disappointing selection of DVDs hit stores nationwide, and with Christmas around the corner you really would expect to see better. There’s a Ben Stiller starring sequel, a fable about a camp Austrian fashion-guru, a high-def re-release of an epic gangster flick and a whole raft of new TV series from Britain and the US.
