Kaamelott is a fair movie but you have to know the TV series, to appreciate the tone and inside jokes. The story is a continuation from the ending of the series. The film kind loose it's sharpness in the middle, and get it back at the end. So, there are parts that feels a bit ordinary. Not much action, and not spectacular. It's a low budget comedy. The soundtrack is pretty good. I give it 72%. It's not perfect and not always well rhythm in terms of pace, but I think it was a nice return to the lore and comedy of Kaamelott.
