My thoughts are pretty much the same. Walter's schtick got old more than a few episodes ago, and now they are just trying too hard (IMO) to just convolute things by having the bad guy maybe not be bad afterall, etc.
And having the whole "Don't you get it? We saved your life! You have no idea who we are or what you've gotten yourself into!" conversation that she just walks away from, and then apparently the FBI completely dismisses. Then Walter and Peter completely blow it off as well.
There's been and are too many shows out now that just want to provide more questions but no answers, and it's doesn't make for good television IMO (although I admit Lost is the best of these types of shows, and I am completely addicted to it)
Oh well...it's still good enough (barely) for me to keep watching for awhile to see where it goes. The characters have not grown on me at all, and I still cannot stand Anna Torv's wooden delivery or whatever she has going on.
