So firstly the fact he went to the battle still disguised made absolutely no sense of any kind, this was the final battle with Morgana to save Camelot and he somehow still has the aging potion on him?! What's more bizarre is that his father even said when he leaves the Crystal Cave he'll finally find himself, and he goes on continuing to hide? Absurd! Here we have the first crime of this finale.
Secondly yes, as everyone has noted the major flaw is he doesn't summon the dragon to help carry Arthur to Avalon. I wish I found some logical explanation for this but in the end it makes completely no sense for him NOT to have gotten the Dragons aid. Why exactly wouldn't the Dragon want to help fore it was he guiding Merlin to try and protect Camelot and Arthur! What is even more sickening to me is that we all know the Dragon numerous times warned Merlin that Arthur must live and the future of Camelot is with him. He clearly states this over an over while warning Merlin to kill Morgana, then Mordred, to name a few. Merlin ignores it all because he's stupid, the Dragon is how old? He's older than any human that ever lived! There is absolutely no way the Dragon wouldn't have been at the battle watching it either, that is all he wanted for Arthur to make magic legal again.
OMG I can continue onward into eternity, how about this.........
So this Dragon flies them to the edge of Avalon? Why exactly? Just fly to the damn island you're a magical creature there's no reason or sense to stopping midway, ahahaha. And this nonsense about the Dragon telling him Arthur was always meant to die? Absurd! The dragon directly contracted himself from earlier episodes saying Arthur was meant to become the once and future king and bring magic back to the land, how can he do that now that he's dead, answer is he can't. No he didn't bring magic back by the time of his death, and neither did Merlin just because he used lightening at the battle do you think everyone was looking up in the sky to see what was happening when they had blades at their backs? No. Merlin doesn't bring and make magic acceptable now just because of one battle, if anything people will just fear it more because Morgana used it and some weirdo person appears killing. No one knew who helped them so why would they accept magic now?
Gwen sure wasn't to upset after her husband dies, neither were any of the knights either, did you see them standing in the hall pronouncing their Kings death? STUPID. At most Arthur lived how long after his fathers demise? Not very long if you ask me! AHAHAH Dad may have been right then huh? One thing I found amusing was Merlin not telling Arthur (he had no chance too!) that he killed his father accidentally, this would've made the ending more believable IMO because now Arthur dies without knowing the full story.
Continuing onward we have Morgana still possessing the brainworm thing that infects the knight and gives her the info to track down Merlin/Arthur. But even so the Dragon could've just taken them to the fucking island from the get-go. Or for that matter torched the entire Army before it reached Camelot's soldiers. The Dragon even tells Merlin he's old and will soon die, why not aid Camelot instead of dying elsewhere?
All indications from the very beginning of the series are that this Dragon believes Arthur must survive, not die in some pointless battle that would never have happened had they stayed in Camelot's castle. With the Dragon broiling people outside it's walls the battle would quickly end, ahahha. I mean holy christ mother of god they end it in such a simple minded manner as to make me sick. I have 10x better endings than theirs!
Also if Merlin is the most powerful sorcerer to live, can't he prolong Arthurs life by doing SOMETHING, ANYTHING? Guess not!
In all the series was pointless, Arthur dies, Gwen gets the thrown (and I suspect she's still possessed by the darkness and is evil) and Morgana dies which would've happened if Merlin had actually listened to the Dragon from the beginning. But aside from that fact Merlin forgets to summon the Dragon to help save Arthur which was wholly what it wanted to do from the very start of the series, keep him safe so Merlin and he could bring magic back to Camelot. But no sir they won't be doing that now because the Dragon is obviously dead (killed off in the film Reign of Fire) and Merlin is an old man with tattered clothes because why? He served only Arthur? Sorry but he actually has to do something useful with his time apart from that now that he's dead and Camelot is gone!
Merlin would not continue roaming around aimlessly for no reason when Arthur was dead, especially not for thousands of years or whatever it's been at the end. Anyways I can think of more shit to say but wow what a wasted series, it's worse than Quantum Leaps ending and that crap wasn't even given time to rewrite, they just cut up the finale there to make an alien into god (read more on Google about how it was going to lead to another season in Space).
Well I'm done, hopefully this brings out some people with useful comments, the ending was rushed and not thought out + absurdly done. I am not sure if the writers or whomever were vindictive towards their audience since the show was being cancelled or what, sure seems like they wrote it to get some revenge by providing us a bad ending.
