First time viewer and I’m shocked at how much I liked railgun and how much I disliked index

My first exposure to this franchise was gigguks video so many years ago and ever since then I’ve always wanted to dive in so this year I finally did, I watched the index anime and then I watched the railgun anime and I just can’t understand how index made me almost not watch the show and how railgun made me excited to continue watching this world. Index felt super dated with Touma being your typical harem protagonist that every girl wants like it was so common in the 2000s, every single character in index was so boring and uninteresting except for a few moments touma has. I pushed through to railgun and railgun my goodness, every single character I found interesting, the whole cast is so fun to watch as a whole and the fact that they give entire eps to several characters that aren’t even “main” characters just made me love this show even more. Railgun also makes academy city feel wayyyy more alive and like it doesn’t revolve entirely upon one guy with a magic arm, it made me appreciate the setting way more than index and finally to top it off the animation makes things so much more interesting than the animation index has. Index by no means has bad animation but it felt so boring because all touma could do is fight with his magic arm and made fights really damn stale. Railgun on the other hand when everyone is using their powers especially in that last eps of season 1 allowed the animators to flex and give us some super hype moments. After just finishing season 1 im excited to watch season 2 of railgun and everything after it, I do hope I enjoy index season 2 more because I don’t want to hate it but after the first seasons of both shows yeah Railgun is much more interesting to me
