I liked this one a lot. I generally watch cartoons with my daughter, and we were looking forward to two. Marvel's Super Hero Squad had been highly recommended and seemed ideal for us, and the new Spider-Man show, which was almost an afterthought.
I really disliked Super-Hero squad (click here
for my post on why), but we were just astounded by how good every aspect of Spider-Man was. We're eagerly looking forward to the next episodes.
