Well, Disney had the brilliant idea to use one of Marvel's most popular characters for marketing. No sarcasm there, it's a good move from a business perspective but as a fan I really hate what they do with Spidey, or Marvel heroes in general. It's odd how Marvel has great live action movies but when it comes to animation it all falls apart.
Instead of catering to everyone like with the movies they choose to go primarily for young audiences with the cartoons. And thus we get lifeless shows like Ultimate, and the Avengers cartoon. Marvel heroes deserve better than this.
As a fan I hope they cancel both this and the Avengers cartoon and start all over with a more serious approach to the characters, with no chibis, no pointless gags every 5 minutes, no team ups with characters I don't care about, no Spidey acting like a 12 year old fanboy towards the Avengers, no obvious marketing for the movies etc.
And by serious approach I don't mean grim dark, swearing, over the top violence and blood like DC does, don't worry.
