As anyone else would note in this review, recaps are recaps. If you find recaps skippable generally, then there's nothing about these that's worth seeing either. Frankly, I don't see a problem with taking another 20mins or so with a quick refresher (especially if I'm not exactly bingeing the show), but if we disagree on that, then we disagree. I'm not here to preach about how recaps aren't all that bad.
But yeah, even if there's nothing great, there's nothing horrible or lacking here either.
I WILL note that the third installment took me off-guard compared to the other two. While they all functioned as recaps, the third special here reached farther back - clear to the beginning of the series - and created something more akin to a hype-promotional video than something that's strictly a recap. Gets you pumped to continue the series.
