For people who are getting into NJPW, they probably don't give a fuck that JR messed up. There's too much information to take in, and yeah calling LIJ "NWO and DX Lite" is a fucking bad call, but I can at least understand the logic behind it.
The show was good enough where the commentary wasn't going to make or break the thing.
I went back and watched parts of WK9 with JR and Matt Striker's commentary, and it was just as bad. But as someone who didn't know shit about NJPW watching the show for the first time, none of that stood out to me. (JR and Striker completely missed the last Bomaye to end Nakamura vs Ibushi, and seemed confused that the match was over)
Current fans go "This is NJPW's big entry into the states" but want every detail to appeal to THEM instead of the new people (who they are arguing the show is for).
