And with Spiderman 3 there's Sandman, Venom and the second Green Goblin. With these movies, it's often the fault of the three villains taking up too much screen time, distraction too much focus from one another to make a good dynamic.
For this one, hopefully they learn from these previous mistakes and try to keep most of the focus on Electro while giving the other two impressive battles building up to him. Rhino's a superpowered thug and Hob Goblin's a mercenary, so they make great lackey material when compared to Electro, suitable for a fight or two like bosses preparing Parker for the big finale.
