Hmm, think for me you pretty much hit the nail on the head. I don't like the conspiracy theories in 99% of the show - and these days it seems every show has to have one, from NCIS, The Mentalist and Castle all the way up and down the dial. I much prefer the straight ahead episodes and ignore the bits with the conspiracies so when they devote the whole show to that part I tend to stop watching. If a show is all about the conspiracy all the time I find very few interesting enough to watch unless they are really well done. That said I do have a few favourites with 24 being probably one of the best - yes I am willing to suspend my disbelief of the real-time time-line that can't possibly work.
