While I was expecting (and looking forward to) a new third person adventure.
I'm not really disappointed that it's an on-rails shooter. I loved RE:UC and House of the Dead Overkill.
Hopefully it won't become a trend though. I feel the Wii would do well in third person shooters, as Resi Evil 4 has proved, and I don't want my gaming sessions to be hampered with lack of a Wii controller.
