Whatever marketing genius decided to divide a TV season in half and sell it to the public for twice as much deserves rotten tomatoes. If you buy it on Blu-ray the entire 4 seasons plus The Plan are an excellent deal. I now will avoid all purchases of a DVD selection that calls itself "Season 2.5" or "Season 2.0" or something like this. That's the indicator that you're being cheated. It was a really, really bad move. The entire 2nd season on DVD costs over 70 dollars this way.
What's not so great: the packaging of the season episodes cheats the customer.
