I must confess that, most of times, the chemistry of Merthur worked for me. But the first reason why I liked the show was this kind of hysterical way of acting of Colin Morgan. In fact, all the chemistry with CM worked : Merlin/ Gaius, Merlin/Gwaine, Merlin/Morgana, etc.

I'm pretty sure too that the actors signed up for five seasons, but this doesn't mean that the whole show was already planned, it is obvious that it was not. As the producers found that the bromance worked very well for the viewers, they sticked to it in spite of any logic. The logic commanded a progression of the Merlin/Arthur relationship after the death of Uther which never happened because of the success of the Merthur thing. That's why the in extremis reveal made no sense. Nobody can explain why, suddenly, Merlin decided to tell the truth to Arthur. "It was the last episode", was the only reason, very poor reason indeed !
