How do you feel about the (radical) changes in Metroid:Other M?

Prime sold less with 2, the one that added a more linear structure and more narrative. It sold more again in 3, but much less than the first Metroid Prime.

This is a radical oversimplification of the factors that lead to Metroid Prime being an uncharacteristic success for the series whereas its followups were more in keeping with the series norm.
