I think ff4:tay is good if you want to spend more time with the ff4 cast, but the plot is nothing special at all. also out of the 12 new (permanent) party members, 7 of the them are not good like at all.
My Final team Was Ceodore, Ursula, Leonora, Ursula, and "Theodore" (not his real name on the last one, but people who know ff4's story will know who im talking about), those characters i did like and were fun editions to the cast, especially Leonora, it was nice having a party member from the one major nation in ff4 that didnt have a party member in the original game, and i think her love story with palom was ok. also she had a a "disability" in the form speech impediment and it wasnt treated like something that needed to be cured or that made her completely unable to function as an adult
