I've watched through each of these, twice!
Here's my take on their types, listed according to the ones I'm most sure about first:
Neil-- IEI or ILE (so hard to tell given his erratic nature, but def. irrational)
Lynn-- LSI or ESI
Any thoughts on these? Or on the series as a whole?
Also, if you haven't seen them, it's totally worthwhile. Get them from the library and watch them one after the other. You'll watch their lives flash by and it's quite affecting.
