Spoilers
The first 25-30 minutes was more like a gimmicky comedy. Warner Brothers was even mentioned. The plot seemed lacking. I liked the idea of Neo and Trinity in an alternate matrix rebuilt to create more energy. Reconstruction and all was cool. Swarm was cool. However, why would machines help them break the system? If the energy balance was broken then it didn't work...that was brought up in the first Matrix. NPH was the wrong person to cast and why did he have control over Trinity but also Neo. Weird fight scene with exiles and Mr. Smith. Why did Mr. Smith become a friend? I'm sure Matrix fans are happy to have something, but overall it was a hodgepodge of poorly laid plot lines. Paint the sky with rainbows... Again it felt like a long star-studded reunion with no real ending; that made sense anyways.
It felt overly long too.
