I am currently watching old episodes of The Apprentice UK fourth series (via YouTube).
I am absolutely hooked!
There is a lot of in-fighting, untrustworthy characters, spin etc. Not a good side of human nature, but the tasks are interesting and some of Alan and his aide's comments are legendary.
Micheal's winning outburst after the greeting cards challenge (and Margaret's reaction) was something else.
I have seen series three but think four was better (well at least so far).
I have not seen other series so keen to get some feedback on which one you think is the best
