I love Christmas episodes- especially in cartoons. Gwen and Peter continue to dodge each other, while Peter's confused hormones might be pointing him towards Liz- who's still tending to the injured Flash. The human dynamic between these characters was nicely done- especially in the scene at the ice-skating rink.
Unfortunately, a new Sinister Six has been assembled, which includes Sandman, Vulture, Electro, Ryhno, Mysterio, and.. Kraven? Interesting combination (I know the comics have had many different members over the years). They plan on bombarding Spidey, and wearing him down in teams- which almost actually works! But of course, the wall-crawler pulls through. Good ep.
