Meltzer definitely makes mistakes, but I don't blame him for getting pissed on Twitter at idiots accusing him of being on the AEW payroll and blindly hating him based on known bullshiters. To some extent, it is how the medium is. There is no space to make a nuanced post like Thread Killer's so snark and insults are the bulk of a majority of responses. He actually retweets a lot of cool historical stuff and talks about pro wrestling, so I enjoy him on Twitter. I think he is nuts for thinking the tag team match at Revolution is the greatest tag match of all time, but him talking about that also meant a bunch of fans watched Fantastics-Midnight Express - he actually found a dailymotion link to the match and posted it - so I don't mind it at all. Recently he also gave a brief rundown of the evolution of escape the cage match rules in various territories. If someone can tune out the standard Twitter toxic bullshit, there is some good stuff there.
It is clear that there is a style he loves and it's not a style that appeals to everyone. But, as mentioned above, he has been very hard on AEW on multiple occasions. Maybe it gets lost amongst the cacophony that is Alvarez ranting about everything.
