The control mechanic of blasting something from a FP view and toggling quickly worked for me once I got used to it.
It was actually quite satisfying to dodge blasts from a boss and then quickly shift into FP view to blast a bomb back right into its weak point.
Required skill and timing.
Honestly if you cut all the Metroid theme/lame story out and called this game "Razr Blade: Matooor Badass Nintendo Heroine" or something (lol), most people would probably be heaping praise on it as one of the better action games of the last gen.
