Don't listen to anyone telling you different- Vanished is tied for best new show of the season with Jericho. People may say that it's not Lost- thing is- that's a good thing- the arc is far better thought out than Lost- there are intriguing teases every week that actually tie to the mystery- unlike the irrelevant baggage Lost carries around with it.
Vanished is a very addictive show, and the fact that it follows one compelling case makes it all the more exciting- for example there are no pointless characters- like the prevalent 'comic-relief' character we get in almost every show now.
True Vanished is not the best show of all time- some of the acting leaves room for improvement, and the senator's daughter is a little bit on the annoying side, but at least we get varied characters, which is something you only usually now get on veronica mars and grey's anatomy.
The real tragedy would be if this show gets cancelled before it finishes its arc while Lost blunders on not ever planning to wrap up any of its mysteries.
