They've only had two episodes, but I've only seen one of them. Most of it's Lucha or older hispanic wrestlers who worked in various promotions, so the only person I "know" is Prince Puma / Ricochet, but I liked the matches we got in that first episode.
The commentary is pretty good w/ a lot of back history (and even telling you to go search for specific matches on youtube for more info, lol). It has a few legacy Lucha people like Blue Demon Jr, but really it's all a huge mystery to me.
