Just my personal opinion--several pages ago, the writing of this story went down the drain and never came back.
Just awful rubbish. But perhaps somebody out there enjoyed it.
Well, the last two pages simply reworked material that had already been on the '91 Series - and that was most likely for the benefit of readers who may not have watched the series and to take liberties with material so that it would fit better with what the comic writers had in mind. Though, particularly with Page 20, they came up with their own dialogue which at times did leave a bit to be desired.
For me, the comics work best when they stick to new and reworked events at Collinwood. When they introduce new material apart from Collinwood they tend to go off the rails, as we'll be seeing very soon (starting with Page 22). Talk about going down the drain! But when it comes to the direction Book 1 will be taking, I somehow suspect the writers felt they needed to add that sort of material to attract "regular" comic book readers who may not have been all that familiar with DS. Who knows? Though as I said before, it does strike me as not only interesting but frightening (and not in a good way) that DCP supposedly not only signed off on what's to come in Book 1, they remarked that if they had seen Book 1's proposed plots while the '91 Series was in production, they would have hired the comic's writers to write for the series! Perish the thought when it comes to the stuff that will take place in Barrettstown!!
One thing I do have to say is, as interesting as I find much of the beginning of Book 1 to be, for the most part I enjoy Book 2 much more than I do Book 1. Though thankfully we haven't seen the last of some worthwhile material to take place at Collinwood in Book 1...
