Tracy was okay to me. I never really liked him, even back when I first watched the Orange Islands, but I never really hated him either. He was just kind of there, which was part of the problem with his character. Despite how he was the first character in the main cast that didn't have a video game counterpart or wasn't based on an already existing character, he didn't stand out that much at all. He mainly stood on the sidelines during the action, didn't have any memorable moments with Ash and Misty, didn't have much of a personality aside from being a huge fan of Prof. Oak and pretty much didn't have any kind of development. He was likable enough, although I never liked him quite as much as I did Brock, but he didn't stand out that much at all. So, he was one of those boring yet likable enough so I can stand him kind of characters to me. It's kind of nice that they have him appear again and even some brief references even in BW, but I'm glad that he only lasted one journey. I didn't really see much of a point in him sticking with the group past the Orange Islands, especially when he clearly wanted to help out Prof. Oak, and I doubt that it would have led to much of anything for his character, aside from capturing a Smurgle in Johto. Still, he was a decent enough character, but nothing really memorable to me compared to characters like Brock and Cilan.
