This won't be a full review, other's more qualified have done an excellent job already. But--as A recent purchaser of the 5 series box set, Amazon have invited me to say what I think. Although I was aware of it ( and the themesong),I was a very latecomer to this series, having discovered it on late night C4 repeats. This is U.S TV comedy at it's very best, consistantly sharp whitty dialogue, beautifully delivered by an excellent and well chosen ensemble of experienced actors. It must be the devil of a job to find an original comedy theme today, that works so well and presents so many facets of human interaction, in such a confined scenario. They have extended this, as all long running series do, ie. adding charactors and using occasional outside filming, to broaden the potential story lines. I cannot finish without mentioning the truly wonderful performance of Jim Parsons, who plays the very original charactor of Sheldon Cooper, because clearly,( all awards totally justified), when the writer's conceived of the idea of a bunch of techno super-nerds, who at the same time have zero social awareness skills, and living in close proximity to each other-they MUST have had 'Sheldon' in mind as the main cornerstone of their creation, and the rest were built around him. In short, I don't think the series could have survived without him, he is too key a charactor, despite the brilliance of the other ingredients. Highly reccomended. P G Croft.
