This was a fun and adventure-themed episode, I enjoyed watching it. It's nice to see Alexa tagging alone with Ash and co. to find the hidden trasure in the deserted island. I liked the part where Team Rocket was talking about Rudy, Sapphire, Diamond and Pearls......it reminded me of the older generation Pokémon games.
The battles were good, but they're too fast. The battles happened too quickly and the attack animations were so fast, so I couldn't enjoy them as much as I enjoyed all of the battles in "The Journalist From Another Region!" The only battle I enjoyed, was the battle between Charizard and that wild Ninetales. I loved how Charizard owned that annoying Ninetales with Dragon Tail, it was great to see him in action again after so long.....But I think It would've been better if the battle was longer. Too bad Ash and co. didn't get any evolution stone at the end, but I think it's for the best.
As for the dub, it was pretty good. Alexa's VA is doing a good job voicing her, I'm really liking her English voice. TPCI didn't kept all of the Japanese music in this episode......I guess they were saving money for licensing all of the Japanese music for the first two episodes of the XY series(which is a good desicion IMO).
