First review in for Metroid Prime Trilogy, from the Official Nintendo Magazine UK. They awarded it 94%, praising almost everything about the compilation.
Metroid Prime was praised for being such an epic adventure and criticised for too much backtracking.
Metroid Prime 2: Echoes was praised for having some sublime level design later on and criticised for the frustrating Dark World.
Metroid Prime 3: Corruption was praised for great atmospheric gameplay and criticised for lacklustre boss battles.
Overall, the package was received extremely well by the reviewer.
Notable changes were brilliantly implemented controls across the trio, decreased scanning times, proper widescreen support and a unified emblem mechanic derived from the third game. The writer also claims Samus appeared to move faster, but wasn't completely sure.
Encouraging signs...
