I'd probably say no. I personally wouldn't watch them myself.
This is going to be a bit difficult to talk about with the whole "no religion" rule, given the very strongly religious themes in "Left Behind". But in any case, from what I know of the books, and probably any movies based on them, is that the basic plot is that God has taken all the true belivers up to heaven, and those left behind are suffering in the final days before the Last Judgement. There's supposed to be a sort of message about the whole thing, that the people left on Earth are getting what they deserve for being sinners or something. Like I said, forum rules dictate that I pretty much have to step around this carefully.
