My wife and I have been watching Season 1 from the beginning on TNT - in HD - and it's amazing to see how GREAT the series was back then. It had a real sense of fun, style, and genuine emotion. Jennifer Garner and Victor Garber were extremely fascinating to watch and were showing off some amazing acting skills. Michael Giacchino's music scores were heart pumping and accompanied by some amazing usage of popular songs.
Now, the fun has been replaced by scowls, the style is run thin due to Garner's pregnancy, and the genuine emotion has been gone ever since Bradley Cooper's character left the show. Giacchino is being streched too thin between this, Lost, and his now fledging film scoring career. Even Marshall isn't as funny as he was before.
I'll keep on watching, but I hope they tie everything up soon, because Alias is running out of gas.
