I love TLB! While I was upset at the dwarves, especially when they began shooting at the Horses, I was in no way "freaked" or "traumatized". (I first read it in middle school, then countless times since.) Some of my other thoughts:
1. While much of the imagery does remind readers, esp. Christians, of Revelation, TLB is not allegory it is "suppositional". This means that Lewis was writing books about characters "supposing" they went through similar events/trials to what we go through in life. While LWW has strong religious themes and TLB has strong religious themes, neither are meant to be direct representations, so Tash does not NECESSARILY represent Satan, Shift does not NECESSARILY represent the Antichrist, etc.
2. It IS interesting that Eustace is not mentioned meeting Caspian again, however we can assume it happened later, as we can also assume ALL the "good guys" are there (including Cor and Aravis, Bree and Hwin, etc.). Lewis probably didn't want to list EVERY SINGLE CHARACTER in Aslan's Country!
3. Tash never scared me for some reason. None of the evil characters scared me, even as a child (though I did not read the books till I was 10-12).
4. While I did feel let down that Lewis does not continue describing Aslan's Country at the end, I did understand that Lewis wanted to leave that up to OUR imaginations. I also enjoy thinking of Heaven as being like Aslan's Country--bigger and better than this world, but yet still recognizable. I also loved the fact that the "Britain" section was connected--through the Mountain--to the "Narnia" section...I guess it is that idea of "other worlds".
