That is a good idea, actually. Having seen that film plenty of times, I feel the show is equivalent to that film.
That being said, I do have one issue with the film, in hat it had Merlin being Mab's son, when he is her grandson in myth. His parents are a human mother, and a certain Fairy King from Avalon, called Oberon.
However, this discrepancy I get, since it has been at least almost 2000 years, and that is not very well known about now. These days, Merlin is Satan's son instead. You could say it is legend fading to myth in real time.
