I found this rant to be horrid because:
1) Lack of substance in arguments. You kept repeating points without giving any evidence, e.g. you keep stating that the controls are shit, so explain how they let you down so much; the levels were unimaginative? Explain what features kept the previous titles feeling fresh that didn't appear/work in this iteration of Mario Kart; etc.
2) Lack of knowledge in arguments. This is mainly aimed towards the "wii is bad cos it's different" claim because it was the only one that I noted you giving any reasoning behind. The reason you gave was that the main audience is made up of 'old gamers' and that 'old gamers' don't like change (what exactly do you mean when you say 'old gamers' anyway?). I'm surprised that there is someone here who doesn't know that wii gamers are predominantly casual (well... all systems have predominantly casual players but the ratio on the wii is far more extreme). Also, what makes you believe that 'old gamers' don't want change? I've been playing since I learned how to press a button yet I'm always looking out for games that try to break the mold.
3) The wii is awesome! While I do have bias towards the wii, all the problems you stated, i.e. controls, I've never had a problem with making me start to believe I'm one of the few that has acquired a non-defective wii. I've found the wii controls to be the closest to pc in terms of precision that I have ever used. Whilst I have yet to play SSX Blur, I know quite a few people that have and they say that the controls are a vast improvement, so I choose their word to be more reliable than yours.
4) Wii bashing is old. The wii is at least one of the most bashed items on the escapist and I have yet to see someone make a compelling argument against it. You are even competing against Ben Croshaw who, as I'm sure you are fully aware, has a rather large following in this style of 'reviewing' and takes any reasonable opportunity to tell people how he hates the wii.
5) I dislike negative rants. Just a personal preference, but I'd prefer it if you'd focus on something you liked rather than something you didn't. Reviews are better if you look at both the good and the bad wherever possible.
6) Where's the funny? Although I don't care about this much, you did label it as a comedy in your previous post and at no point did I notice anything resembling a joke, unless the "What happened to JP" was the light hearted bit but I found that annoying. Maybe I needed to have played SSX before, but you do have to realise that most of the audience won't have a clue what you're on about unless you explain it to them. If you do try to explain though, make sure it doesn't ruin the flow or become obtrusive to those who do know what you're on about.
I hope I haven't dissuaded you at all from continuing to do these, I just want to say you have a lot to do before I can see them as being good.
