I have a love & hate relationship with the magic vfx in this show
This show even with a lower budget really made the magic vfx looked good!. There are times I wish they could've made it more unique instead of just streams of energy blasts. Even so, the use of energy pluses and sheilds are shown very quick in flashes of light (not saying it's horrible).
[Image 1] I wish they made Alice's power red, and not orange because during agathas rage bait, Alice hands glowed red while Lilia glowed orange, so I thought Alice would have more of a fiery red color to it (I guess I could see a little bit of red in her power)
[Image 2] Billy's magic is obviously Blue but it just looks like any normal typical witch with blue magic like the salemmite witches or the witches that agatha killed in ep 9. Tbh it would be more interesting to see Billy only projecting lightning magic at agatha (I know there's like electricity when using magic but I'll comeback to that) just lightning, no wispy streams incorporated.
[Image 3] the circles in his hands looks kinda out of place tbh, I wish it wasn't so 2d. Honestly they should've give the rings to wanda instead.
[Image 4] it looks very flowly in that scene and I just love it! It feels as if agatha is touching mist and is probably one of my favorite scene of her magic, plus her hand gestures is so good!
[Image 5] So about the whole electricity thing happening while using magic in this show is that, I lowkey hate it and love it. I know its probably a design choice for the show but I really don't wanna see it used in other future projects. It would make sense for Billy to only have electrical elements to his magic because of how he first only used lightning powers in the comics. But the electricity also makes the scene of ep 9 where agatha absorbs witches powers look very awesome and powerful like agatha is gaining energy from the magic which I sorta love!.
This is a long tanget but these are my thoughts, overall the magic vfx are great for this shows design choice, I just like Wandavision magic effects better, if not bring back something like Age of ultron Wanda's vfx powers.
