Do you not have much room behind the TV?
to function properly the remote needs to be at least 1 metre away from the sensor bar, which is a tiny distance so you shouldn't be too close, hell my room is a box room at the moment, the TV is at one end of my bed and I am at the other (so my arm in the middle is about 1.5 metres away from the screen) and it works fine.
Medal of Honour: Heroes 2 is supposedly a pretty good shooter for Wii, as is Red steel from what I have heard (except for a few flaws)
Metroid Prime 3 is amazing too.
CoD: Waw for Wii seems to be a love/hate thing, but it might just be the usual schitzophrenic nature of traditional game reviewers doing a Wii game... which probably means it is a good game.
Personally the only shooters I have are Metroid Prime 3 and Resident Evil 4: Wii, both are incredibly good and well worth a purchase.
