All parts were great, Charlie and Dee were funny as were the bar scenes. Also at first I thought this global warming theme will quickly become overplayed but I must say they did a very thorough and interesting analogy with the bar scene and also Dee's and Charlie's adventures. The lacking resources, overpop., the plastic, water, the hypocricy of everyone involved, be it those in charge or those selling "solutions" for significally marked up prices, etc etc... there were a lot of little gems and methaphores, Im sure I did not even notice all. Would call for a repeated viewing.
But all in all, i missed a really funny ep like this from Sunny this season, up till now they just havent been cutting it as usual. Nice one!
