Review on the last episode of 'Merlin'

I love the Merlin series, I love how they have portrayed  the Legend of Arthur, I think casting is brilliant and the scenery is fantastic! Bradley James plays Arthur superbly and Colin Morgan is perfect for the role of Merlin, in fact I think this series could've gone on for years, they did not do the quest for the holy grail, they did not include Lancelot's son, they did not do Gawaine's quest and many more parts of the Authrian legend they could've done. However they ended it abruptly, which meant that Morgana's death was less than one minute, Arthur dies far too young for audiences pleasure and it did not show how the rest of the charaters coped with the King's death, they simply showed Gwenevere on the throne, I am sure that many people would've only wanted Merlin's magic to be revealed in this episode because we never saw them together and Arthur knowing he has magic, overall the BBC should not have ended the series with such a poor ending, and they have been penalised by the audiences.
