Query: Too Slow!

I've read all the books in the Left Behind series. The 1st (Left Behind) was excellent and I couldn't wait to read the next 2 (Tribulation Force and Nicolae). They seemed to slow down a bit, but still kept me interested. Soul Harvest and now Apollyon have been entirely too slow and the characters don't really interest me anymore. The dialogue seems forced and stiff. La Haye and Jenkins need to slow down themselves and take the time necessary to generate a good product - a book that is not slow-moving, but has more action and substance. This subject matter is too important! This series still has great potential and I'll probably continue to read the books. I'll just be sure to check them out from the library next time!
