An enjoyable review, and I agree with a lot of it, but there is some, namely issues with the controls, that I feel were not adequately explored. Let's start with what I agree on:
First, the level design. It's very unimaginative repeating corridors, leading to a big room where you'll duke it out for a bit, then more corridors, then another room, then corridors, etc. until you reach the end of the level. There may, occasionally be some side rooms to explore, but they're mostly there to hide hidden text and data disks, and to allow enemies to jump out at you. Next, the enemies lack variety. There are some new ones added as you play, but you'll mostly be seeing the same faces throughout the game. The story: Oh, it's a conspiracy story, with a secret government agency, and aliens, who are working with the agency. How quaint. It's not that the story is bad; it plays it safe, and as a result feels rather lackluster. Finally graphics, they did make a powerful engine for the Wii (again, by the Wii's standards), and they did manage to incorporate graphical techniques developed on and for more graphically powerful systems, but you totally won't notice it. The problem is that, while the character models are particularly good, the environments didn't receive the same treatment. I wouldn't go so far as to place it with PS2 games, it's atleast on the level of the Xbox, but they honestly needed to spend more time implementing their graphics engine capabilities.
Now I did like the voice acting, what little of it there was. I particularly liked William Sheppard's acting as the villain. It was very convincing. The main character was voiced by Mark Sheppard (son of William Sheppard), who also did a good job. Then there's Kevin Sorbo. Kevin Sorbo is one of those actors who can only play one character, himself. That's not to say he's a bad actor, he does have a very nice voice, but he certainly pales in comparison to the like of William Sheppard. There are no awkward, or corny lines in the script, it's well acted an flows well, but the story itself is average, at best, nothing to make it stand out from the crowd.
Before moving on, I'd like to point out that, contrary to Yahtzee's review, there is a backstory to the game, which can be found in THE GAME MANUAL. Yes, they took a page out of the NES days, and put the story in THE GAME MANUAL. Major news events of the past 6 (if I remember correctly) days can be found at the beginning of the manual. Here, it also explains why YOU ARE THE ONE (I understand it's cliched, but at least they do explain it). Apparently, you where a member of the President's bodyguard, and single-handedly saved his life when all the other bodyguards attempted to kill the President, I guess you didn't get the memo. You were apparently selected for your exemplary performance.
My last beef with this review, is the controls. Yahtzee's complaints are real. If the cursor goes off screen, then the screen gets stuck until you have the cursor back on screen. But, and this is the important point, these complaints are only true with the default settings. The other major plus for this game, which went completely unmentioned, was that literally every variable for the controls is open to modification (with limits on the values of course). You can adjust the turning radius speed, your running speed (not online though, it's set universally to 80 online), wii-mote and nunchuck sensitivities, viewing angle radius (so when Yahtzee complains of not seeing a demon spawning Alaskan governor on the ceiling, he can go into the menu, set the vertical look to max, and then he can actually look up to see the monstrosity). By playing with the settings, you can iron out almost all of the complaints he made.
Last, there is at least one original weapon that deserves note, the shrieker. It's essentially an alien grenade launcher, which allows you to guide the grenade through the air. In concept, this is very cool, but in practice, it's very finicky. The weapon has amazing potential, but would take hours of practice to master.
