How disappointing !
As a huge fan of the Last Kingdom series, I was very exicted to see the movie that would wrap everything up.
I understand that finding a new plot was not easy and I don't think anyone really wanted a drawn out fight between Aethelstan and his half-brother.
I also don't have any problem at all with the writers making Aethelstan gay. Why not, there have been gay kings throughout history.
The big problem with this movie is that the writers have completely perverted his character. The boy who was brought up by Uthred and whose ability to see clearer than most is turned into a dim-witted tyrant who is prepared to kill and murder for the sake of a lover. This lover in turn is a very uninteresting character, whose motivations for murder and destruction turn out to be rather pathetic and hardly believable.
During the first half of the movie, Uthred appears to be an unready innocent, shocked again and again by the crazy decisions of Aethelstan. The nations of Scotland and Wales, which were so proud and strong in TLK also just accept humiliation and taxes without a fight.
It is also sad that there are no strong female characters in the movie, even though they were essential to every season of the series.
The ending does bring some comfort as Aethelstan regains his brains and Uthred is awaited in glory at Valhalla.
Overall, the movie is frustrating and does not respect the legacy nor the storylines of the series.
