In Jericho, the writing isn't as good as it could be, the main idea is interesting and yes there's a lot of shooting.
In Lost, several mysteries in each episode, connections between everyone and few answers at the time (it's amazing to see how everything connect and for those who have a good memory to see that everything fit togheter). I'm watching it since the beginning and I can't wait each week to see what will be next. I'm very interested to see how everything will end with that show. + I like the idea that they aren't affraid to kill a main character if necessary.
I have to agree that a lot of shows are made in the same mold.
But like I said before It isn't because I like apples that everyone will like them.
Thanks Jude and Phlebas for you input.
