The only problem with Wii FPS controls I'd attribute to the Wii itself is being forced within the border of your TV (Red Steel 2 somewhat fixes this with motion plus and the PS3 diddle stick is another solution). A big problem is that the games have a narrow field of view. Pull it back or even make the games third person and it would help a lot. The entire gimmick there is that the wii remote is supposed to be your gun, but that breaks as soon you try to turn. To remedy that, devs make the screen act as one large analog stick, which kinda removes the idea of the wii remote in the first place. It's not accurate, fast or reliable. The gimmick is neat though, but both the tech and aspiration of the devs are limited. I mean, what are the chances that a small team working on a port of a two year old game would really try and fix any problems.
The port itself doesn't look too bad, though. Against FPS games from last gen, it looks solid. If you stack it up against CoD4 360/PS3/PC it would look a lot worse, but for once it's a game that looks solid given the Wii hardware. Most of the time devs don't bother at all, and rightfully so (see: Quantum of Solace Wii/N64)
