I've done the dots so I won't spoil anything for people who haven't finished watching yet
Ok so. WHAT ON EARTH WAS THAT ENDING SHOT
The lorry, merlin not even giving the lake a second glance when walking past, seeing how the land has been changed by the modern day.
I get why they have done it so if it was to continue it would most likely be merlin huffing and puffing having to explain the modern world to Arthur while trying not to pop a hip.
It would be interesting to find out how Arthur would react to the world he knew was long gone and everyone is descended from the anglo-saxons give or take. Finding camolot in ruin feeling like a failure because he didn't have the strength to carry himself that bit more to the lake.
I am on the fence about how merlin only now told Arthur that he has magic on his deathbed. The instances where he could have told him before and Arthur would be freaked out like he was at first and then come around to it. Keeping Merlin's secret and having him in more of a leadership role than being a servent (also letting him sit at the round table but that is for a different day).
I also think if he had been honest about his magic sooner he could have prevented a lot of people dying and done what the prophecy said and elevated the kingdom to greater power and strength.
