Without getting too much into it, I've always felt that Dragon Gate had a very specific insularity to it that other puro promotions don't seem to have. The style is different, the roster and presentation is different from the rest of the major puro promotions (also, the roster seems to rarely change; the major guy they were seemingly cycling in left with CIMA), and the booking/storylines are actually quite a bit harder to follow in terms of beginning and end points, since relationships tend to have long, convoluted, and necessary multi-year histories behind them. You may not need to know about Ibushi's history with X wrestler to enjoy his angles and matches, but that's seems to be much more of a requirement in DG (in my opinion, at least).
Given all that, it's not a surprise that it has an ardent and dedicated fanbase, but also people in America seem to care less about it. There are guys who are or were somebodies in DG that have no rationale for being somebodies unless you sift through a decade-plus of semi-necessary history. NJPW newcomers are running into that stumbling block now with people like Goto, but you don't absolutely need to know Goto's history to care about him and his matches.
That's just my view though, I might be wrong. But I do think there legitimately are major aspects of how DG works as a promotion that factors both into its appeal and its lack of accessibility for newcomers.
the stuff with Goto and Naito have nothing to do with this G-1 breh.
Everything I wanted 
Shingo/Naito was excellent as well.
