Fantastic 4: Rise of the Silver Surfer is a fitting sequel to Fantastic Four.
The good. Better A story, with sensible B and C story. Incredible Galactus effects.
The actors. The same.
The bad. The humor is not as good, if still present and done on the same tone. It lacks a bit of polish and the best example of that is that it tells a larger story in much less time.
The ugly. Nothing really obvious.
The result. If you like the first one, you'll most likely like this one too.
