The final episodes of the successful series do not quite manage to do Merlin justice.
When you watch a series for years you begin to develop ideas as to how you expect it to develop. Your familiarity with the characters and concept means you are able to make informed guesses as to what could happen and often you are not that far out. Of course it is better if shows do not conform to those expectations and do something completely unexpected though sometimes you feel this is not the best that the series could achieve. Merlin does just that as it comes to a close after five seasons.
Beware- if you’ve not seen it there are spoilers past here.
