See, I think the exact opposite. All the good shows on American TV are on HBO (Deadwood, The Wire, haven't seen [/i]Sopranos[/i]...too much of an investment). There is of course Mad Men and Battlestar Galactica (which I think is good, but exhausting to watch) on basic cable, and Pushing Daisies on network TV. But that's maybe 8 shows. It seems you forget that American TV has over 400 Channels, easy. And while I enjoy me some trashy TV ( Wife Swap the various house flipping shows on TDC, TLC et al.) I often long for TV that doesn't assume I'm retarded or on a sugar high. I like watching Ross Kemp's show on gangs, and all the BBC documentary series, and, to be completely honest, I really like watching Top Gear. I'm not a car person, but it's so entertaining.
y I liked the first season of Life on Mars, but the show went into a steep nosedive in the second season and had one of the most disappointing finales I can remember seeing. And I disagree with the person who said Peep Show hasn't been as good lately. I think the first three seasons are, overall spectacular, and while the later ones can be hit or miss, when they hit, they hit motherfucking HARD. Plus, repeat viewings of the episodes oftentimes end up being funnier than they were the first time around, which is rare in a lot of comdies.
