I really love the concept of this show....too bad the writing is so painful. Way too many "Hallmark" moments and constant chaos happening. The characters are in fight or flight mode pretty much all the time, to the point that it just becomes so utterly unbelievable. Yes, it's supposed to be somewhat unbelievable, a plane showing up 5+ years later is a very cool storyline. I just can't pinpoint how much of the problem is bad acting or poor writing. I gave up and fast forwarded to the end of season 3, won't bother with the 4th.
