While visually spectacular, it seems kinda meh overall. Not much of a storyline that makes sense. At the beginning it's like ok here's some spiders. Oh and here's some dragons. and now some trolls. No rhyme or reason to it. Then later we have Voldemort and death eaters, but then Dumbledore runs them off with harry's patronus? That's not really what a patronus does.
Granted this is one viewing, of the initial show, on a cell phone video, with some of the effects missing. I'm sure live it's a great show to experience. I'd probably go watch it every night if I was there. Just seems that it's lacking in story.
