You are not George Lucas

Spiderman 3. Looked forward to it after spiderman 1 & 2. Villain 1 and hero were friends, they love the same woman. Villian 1 wants revenge. Hero becomes villian 2 himself. Villain 3 arrives unanounced. And leaves adbruptly. Heroine is crying, getting kidnapped, getting rescued. Villain 2.5 is a new guy who morphs like hero turned villain 2. Did you follow what i said above? Neither did I.
The directors and the script writers losing the plot somewhere. I call it the curse of the sequels.

It happened to Matrix 2 & 3. Remember Ring 2? Rememer Batman & Robin? Speed 2? Miss Congeniality 2? The list is endless.

Why do they make sequels? To take the story forward? To give the audience more of what they loved? Or just to make more money? Make the best of the brand they created?

Not everyone is George Lucas. Not evey trilogy can beat The Godfather series.
Please stop
