I'm just glad that the quality of the plot already seems to have improved.
Nope. It hasn't.
Ive said it before and applies here, too - giving powers to regular human supporting cast in Spider-Man ruins the story. It is vital that the humans in his supporting cast stay human. It's essential to the character of Peter Parker given the theme of the struggle between a regular person and a super hero.
Giving weird powers to regular people - ESPECIALLY temporarily - is weak writing. This is terrible.
Its made even worse by making Lizard into some kind of caveman out of time.
