Though, Trini is my favorite of the original five, but honestly, nobody really started to be developed as characters until PRiS. Hell, even then, LG and PRiS left a lot of their characters underdeveloped. Like I didn't give a poop about Kendrix "dying" in LG because they barely did anything with her.
Honestly, considering the lack of development or even detailed definition, one's opinion on early characters is probably subjective beyond most concrete attempts at justification, just because there's so little to them. The most specific thing I can point to in the original team is their being a balanced group of contrasting and clearly defined, if broad, personalities that interact with each other in interesting ways. Adam's being kind of quiet and insecure earlier on was at least something, but it kind of disappears and eventually his personality becomes as nondescript as the other replacements. They all kind of just seem like generic wholesome kids. It seems like the narrative hoops the writers had to jump through when writing out Jason, Zack and Trini kind of led to them forgetting to clearly define their replacements' personalities, and by season 3 it seemed like they were preoccupied with figuring out how to work Kakuranger into the already somewhat messy adaptation scheme while also coming up with a game plan for continuing the series, leaving Kat's Australian origin as her most prominent character trait.
