I find unacceptable to repeat over and over the old cliché of dreams while sleeping or while being unconscious. It was a great twist in "Jacob's ladder", but now it is just an expedient used by writers with no ideas or B-movies writers.
I expected much more from "The Sopranos". The fifth seasons was already disappointing for 50% of it and the first three episodes of the sixth season are much worse. The Sopranos does not deserve such a low level writing.
