I stuck with Dexer all the way to the end. The first two seasons were the best seasons. The Lithgow one was good. But there's an element of disbelief suspension that becomes harder and harder to do as the series go on, and it makes me wish Dexter was a 4 or 5 season show rather than the bloated 8 seasons it became.I'm up to S4 with Dexter and its ok and I hear tell theres a series with John Lythgow as the 'villain' which is ok too, so why not give it a go.
