This being the fourth film, it will take a lot to keep the audience interested in the series (there’re not too many film franchises that get to this point, let alone comic book films). This film will take place a little over a year after the last. Spider-Man continues his war against Kingpin, though he’s failing miserably.
Now, Dr. Connors is deeply enthralled in his research of regeneration, so much so that he’s become very secluded and snappy. At the same time, Eddie Brock is getting very competitive in the photography field (meaning he’s trying harder and harder to do better than Peter, but just can’t). Peter has become quite close to Mary Jane in the last year, but not so close as to not be open to other options. This is shown when Black Cat comes to town. Spidey finds himself strangely attracted to Black Cat, and she the same to him.
Felicia Hardy (Black Cat’s alter ego) leaves her boyfriend, Flash, feeling closer to Spider-Man than the jock. Peter also ignores Mary Jane as he becomes more intrigued with Cat. Peter knows there’s more to Cat than she’s letting on. Cat confides in Spider-Man, revealing that she is under the employ of Kingpin (Kingpin promises to give her superpowers if she does as he says). Spider-Man demands to know where Kingpin’s new headquarters is. This infuriates Cat and she leaves him standing alone. At the same time as all of this, Dr. Connors has made a breakthrough in his research and has decided to inject himself. Connors turns into the Lizard.
Lizard’s rampage soon draws Spider-Man’s attention and a battle ensues. Lizard is beating Spidey very badly until Cat intervenes, saving his life. Lizard flees into the sewers and Cat takes Spider-Man to her place. There, Felicia reveals herself and mends Peter’s wounds. Peter and Felicia become an item after this (though secretly, as Peter still occasionally sees Mary Jane). All of this should happen within the first half of the film, leaving the other half open for more action (don’t get me wrong, the “romance” won’t take center stage in the first half, but the first half of the film is the story of Spidey and Black Cat meeting as opposed to what the second half will be). Spider-Man and Black Cat become a team after this, taking on Kingpin’s forces together (Cat uses inside sources to pinpoint targets). These actions are set aside for a scene or two as Lizard appears again. One part should basically be Spider-Man chasing Lizard through the sewers, and the other part should be an actual fight between the two (my kinda fight, meaning a long fight). Lizard will be knocked unconscious in the fight and will turn back into Dr. Connors. Spider-Man takes Connors back to his family. Spider-Man soon sets his sights back on Kingpin. Black Cat, after acting as an informant for Spider-Man for weeks, finally agrees to make the move on Kingpin. Spider-Man and Black Cat go after Kingpin and, this time with some help, Fisk is finally brought down. Cat goes for the kiss after it’s all over, but when Peter tries to take off his mask she doesn’t allow him. It is in this moment that Peter realizes that Cat doesn’t give a damn about him (she’s in love with Spider-Man). So, Peter goes back to Mary Jane, realizing that she cares about him because he’s Peter Parker, not because he’s Spider-Man (not that she knows that yet). Despite what you’d think, the fight with Kingpin isn’t the climax. The climax comes when Spider-Man has to once again fight Lizard (this time Connors has grown even larger and more monstrous).
Spider-Man barely gets out of the fight alive and he wouldn’t get out of the fight at all if he had not administered an antidote (Connors gave this antidote to Spider-Man after their last encounter). It takes multiple doses before the antidote takes effect, but eventually Connors is brought back. Looking at all that happens here, and all of extra fillers not mentioned, this will definitely be the longest film in the franchise so far. I worry that the “love story” may make the film boring, but considering the personalities of Spider-Man and Black Cat, it should be more humorous than romantic. That, and, with all of these things happening, the arrangement may get sloppy and lose the audience (however, any wounds in this film can be healed by a sequel). Also, (as indication of a sequel) at the end the film, just before the credits roll, Peter and Mary Jane sit on a park bench and a meteorite strikes the earth in an area behind them (the camera will be on there backs and will zoom out, until it is a considerable length from them, and, at the point where the camera stops, the meteorite will just smash into the ground).
