I have watched the first season so many years ago, and now I'm about to start this season and let me tell you, the first episode pretty much brought back all of the feeling that I had from back then when I was watching the show even after all these years. One thing that I would recommend though is to watch Betterman first to get a full understanding of the story, but for the most part, it's kind of optional if you're just wanting to get into it for the spectacle and hotblooded action. With that out of the way, the episode for me is a straight up 10 out of 10 as it immediately gets you right into the action, and if you've seen season 1, you would see that they still follow the same essence and I feel like they amped it up a bit too as animation, and production got a tad bit better even down to the soundtrack. Even the returning characters I immediately remembered as GaoGaiGar is a series that is uniquely distinctive and stands out of its own. It doesn't feel generic at all and I recommend this show as a must watch if you're a mecha fan like me.
