Let's see...
-The reverse holos are a really cool set of cards to get, creating a new type of version for a lot of these already established cards. Helps that the mirror HGSS-style foiling of it looks very solid to complement the old Generation 1 artwork.
-The foils themselves are an excellent recreation of the WOTC era holofoil.
-The Full Arts are quite nice. Venusaur and Blastoise's Megas, Mewtwo, all of them are quite solid.
-The trainer full arts, as
@TokenDuelist said.
-The secret rares, while not rare or valuable, are cool throwbacks.
-It's a set that's fun for collectors, which is nice.
-And, while this is subjective, I think one of the merits of it is that it, when available, gives fans a way to experience those old Generation 1 cards either for the first time ever or after so many years. A lot of people wanted to relive that old magic of opening the original Pokemon cards, so this set provided as close to that as possible while still somewhat being affordable, at the time. Now of course, resale value is up the wazoo, but nonetheless.
I'm not saying it's a perfect set, there's plenty of things that it could have done that would have made it better. Venusaur and Blastoise's holos should have been included, Alakazam would have been nice too (and they can bypass Kadabra, it's been done before). It'd have been nice if the RA's of the starters were their own unique arts, and it was included into enough stuff where people did get sick of it, understandably. But I don't think it's a "trash" set. It has its merit to it, and I wouldn't be opposed to another set like this-say, for the Neo cards or something. I understand why people don't enjoy it, and that's fine, but I'm just giving my input.
