The Amazing Spider-Man 2 (released as The Amazing Spider-Man 2: Rise of the Electro in some market) is a very entertaining movie if watched in 3D, especially the fight scene between spidey and the Electro. I quite like it; but I will say that overall the movie is just not bad - with some entertaining fighting scene. However, what I don't like is that the fighting scenes seemingly too short given that there are three villains in the movie; Electro, Green Goblin and Rhino.
The movie started off with some sub-plots of Peter Parker's parents, before showing Spider-Man web swinging around the New York City before helping the police to catch a group of criminal before missing his girlfriend, Gwen Stacy's graduation speech, and just in time to attend his graduation. Having promised to have dinner with Gwen and her family, Peter Parker is still struggling with the conflict within himself as he is seeing Gwen's father around him whenever he is in his Spider-Man's suit and warn him on dragging his daughter with his decision; and Gwen and Peter ended up breaking up with each other; having so love each other.
Then Harry is brought to his dying father and he was told that he inherited a family disease which will lead him to death, but his father has done some research to save their life, and hopefully he can continue the research and to really find the cure for the family. And with that Harry is introduced as the heir of Oscorp.
At the same time, one of the employee in Oscorp, Max Dillon was forced to work the extra hour to repair power plant and then met with a freak accident which turns him into Electro. Somewhere outside of the city, Peter Parker renewed friendship with Gwen Stacy before Electro make his first appearance and fight with Spider-Man for the first time - before he was finally captured.
Soon when the disease started to strike, Harry Osborne asked Peter Parker to get the Spider-Man's blood as it is the only thing which can save him; which Peter Parker finally agreed to talk to Spider-Man but Spider-Man refused to help Harry Osborne stating that his blood is not what Harry needed but he will figure it out eventually - of course, Harry not willingly to accept the fact that he is going to die soon.
Peter Parker then realized that his father might have the formula to save his friend, so he tries to figure out what his father left for him before he realized that his father was framed all the while, and that the formula only work on his blood and his line; while in desperation, Harry rescue Electro so that he can bring him back to Oscorp after Harry was expelled.
Electro tries to suck up all the power in the New York city and Spider-Man come to the rescue with Gwen and eventually Electro suck too much power until he blows up. Then Harry, now the Green Goblin came and realized that Peter Parker is Spider-Man and that he refuses to save him, so he avenge by dropping Gwen from atop and killing her. Spider-Man captured Green Goblin but it was a big sacrifice for him until he decided to quit taking up responsibility which might hurt the people that he love.
In the meantime, Harry is still organizing research and crime behind the bar. Rhino is part of Oscorp creation and is destroying the city. Will Peter Parker change his decision and fight Rhino to save the city once again?
