No, really. Very minimalist magic gesturing, there.
I mean, usually they show the mystic energies being manipulated in various color-coded ways and there’s a dull roar from the raw magic crackling away and maybe some wind and this movie is all None of that; all of you in the audience have the magical sensitivity of a brick. You’ll know that Merlin’s done with the spell when the dam’ trees start moving, because that’s what would happen in real life. I am kind of amused at that. The Kid Who Would Be Kid keeps trying to get me to take it seriously, it seems.
PS: Now watch: all of the spellglitter got put in during post-production, or something. Because we can’t have nice things.
