My rating is based on multiple factors, all of which will be described in detail.

Controls:  5 stars

The controls are very innovative and unique.  It's fun to aim the Wiimote like it's actually Samus' arm cannon; and even more fun to use the nunchuck like a lasso when using the Grapple Beam.

Graphics:  5 stars

The greaphics in this game are nothing short of amazing.  It takes full advantage of the Wii's capabilities.  The details, particle effects, and the like are beautiful.

Plot:  3.5 stars

For those of you that like a good storyline, Corruption might as well not even have one.  These games have nothing to do with each other except for the Space Pirates, the Galactic Federation, and Dark Samus.  The plot of this game itself is actually decent, but considering the fact that it has almost nothing to do with its predecessors is disappointing.

Comparatively:  3

This one falls short of its predecessors.  The bosses and puzzles are MUCH better and harder in 1 and 2 than in 3.  In 1, I died a few times.  In 2, I died a bunch.  In 3, I didn't die once.  The Wii controls vastly impair your previous ability to have 4 missile types, 4 visor types, and 4 beam types all at the same time.  In this one, you only get ONE of each at any given time.  In addition, 2 was going in the right direction with multiplayer.  This one could easily have had an improved version like that one.

Overall, 4.  This game is amazing and worth the money, but don't expect it to be just like the first 2.
