Query: Terrible, slow, and WAY too preachy.

I've long been enamored with apocalyptic literature; something about a world slowly dying simply captivates my interest. So I was excited to hear of the Left Behind series.The problem, however, is that the series gradually turns into more of an evangelizing text than a quality novel. Long, boring religious asides take up pages at a time while major apocalyptic events are expressed in merely a few paragraphs. Three trumpet judgements seemed to breeze through in mere pages.While I enjoyed the first three books of the series, Soul Harvest seems to be sending it down a slippery slope, degenerating into a long religious tract. At the moment, I am reading Apollyon (book #5), and find it just as slow paced. However, I continue to read in hopes that it will pick up.
