Yep, that's exactly why I stopped watching House after a few episodes.
24 has a similar problem, just stretched out of a longer season.
1. Terrorist Plot
2. Mole furthers terrorist plot.
3. First terrorist plot foiled.
4. Guy captured or killed is small potatoes.
5. New mole.
6. New terrorist Plot
7. New conspiracy.
Etc. But I still watch 24.
However, the networks canceled Life and Terminator, leaving little on TV that interests me. And why try to find something new? Chances are the show will be canceled.
