Yeah I feel the same way, IE there's a clear "before and after the movie" which doesn't neatly split by year.
Of course. We all know Gok is a specific sort of guy. So I can see why categorising is something he'd like to do. But of course, Hasbro don't necessarily make sure things are neat and orderly over the years (as personnel change, as the market changes etc). I guess he's trying to sense the "vibe" of how the fandom DO split up G1, given the ambiguity.
For whatever reason, there's a fair chunk of the fandom that cut things off after the movie, or after 1986. And I think Gok was trying to suss that out.
"Don't" is certainly a viable option.
Yeah that term, and "Euro G1" are both misnomers. A cultural artifact of the the US-centric fandom. "Non-US" G1 would actually be most appropriate, if anything.
