Why is it linear?
Because most of the stuff like hand pannels, morph ball golems and so on can only be activated the first time you see them after that, those became useless. Same with bosses and pirate encounters, you cant face them two times, and that is a mayor issue and the prime saga. Once you beat the game there is noting much to do, except to find retarded misile expansions. You cant go back and show your friends how exciting is fight against pirates, use a hand panel or a morphball powered device and as a result the game became unknown for most of ppl. The game LACKS of action after beated. It becames another useless disc.
In my opinion, its the best metroid in prime trilogy and you can really enjoy it as the best FPS on the Wii. But for the next saga the should fix this problem.
