My wife has watched the show for years, and I'll sit next to her when it's on (usually with my laptop in hand). All last show, though, Simon's voice kept ringing in my ears "it's all just karaoke, like on a cruise ship or something." The new judges are too soft.
I guess it's time for me to weigh in. The first year - second season, I think, we watched it with our daughter..and I did get a kick out of it. After that, I really did not look again. Call me a culture snob. I'm a Masterpiece Theatre (with its different ramifications from mysteries to classics to current) fan. That's what PBS television here in America gets mostly from England's BBC.
My wife and I are both enjoying it so far. Nice to have some mix up from the same old judges, and we think both J Lo and Steven Tyler are good. I don't think any of them are as good as Simon at differentiating between good and great performances, but they're off to a good start all the same.
I watch very little TV, usually something my wife (a junky) has "taped" Even then sometimes there are so many commercials that it's even irritating to watch her fast-forward through them. The only Idol i've seen was the one where the chubby lady from England wowed the world singing. And that was on YouTube.
