My quick 2 cents - Valentina vs Santana is a worthy follow up from their first fight. It's everything I want in a catfight as they both go at it hard and use all of the fun tactics that make a catfight great. Superb effort from both and I'd recommend it to everyone if they haven't already sponsored.
The other catfight isn't as intense, but it's still overall enjoyable. Just tough when its right there to compare with Valentina/Santana.
My nitpick is I don't love the mutual boob mauling to start compared to the slaps, but I get it that the girls are probably more agreeable to that and it's certainly better than nothing to ratchet up the intensity. Less of an issue in the Val/Santana fight as that one delivered the aggressive goodness that was promised.
Another very small thing that could potentially be fixed later on is that the 2nd fight has an interview and the subtitles are in spanish (they aren't for Val vs Santana). All other fights I've bought from Mexican Catfights the subtitles have been in english, so probably just an oversight.
TLDR: if you like hard real catfights between attractive women, Val vs Santana is about as enjoyable as it gets.
