Peter does a great job arresting shop robbers, bus ruins his self-pictures. When Dr. Curt Connors injects himself with lizard DNA to regenerate his arm, that works. Actually, too well: he soon transforms into a dino-like monster, whose instinct spares nobody, except his son Billy. Peter's uncomfortable secret-identity-handicap now spills from bully-abuse at school to utter injustice in his lab job. Written by KGF Vissers

A satisfying payoff to the lizard storyline
11 May 2017 | by stevenyellowSee all my reviews

Right off the bat this episode starts with some classic spidey charm as he stops a bunch of criminals from robbing a bakery, then we get the o so catchy theme song to Peter arriving home expecting bank from the bugle for his spidey pics but alas our hero fails yet again. But my favorite part of this episode has to be the way they handled the lizard, unlike other incarnations this version is just there to cause chaos while his other counterparts has this dumb idea of turning everyone into lizards. It also raises an interesting question "would doc Conners have regained his arm without the transformation if electro hadn't electrocuted it". And at the end we see peters friends fire him because of taking pics of the lizard which not only is a great setup for Eddie Brock's eventual turn as the lizard it also has one of my favorite moments in the show why Peter must not give up being spider man. Another great episode with an incredible ending.
