I've played a few of the Tales games. After Phantasia (which I like a lot), I wanted to see if any of the others were actually good. So over the years I took a look at Vesperia, Zestiria, Symphonia and Berseria. I really tried to like them all. But I couldn't. Lets just say I don't want to **** on the other Tales games as many people here like them. To me I just don't like them. Objectively bad or just bad in my opinion? I'm not so sure yet. I'll need more time with them to work that out.
I just finished my playthrough of Vesperia several days ago, and it was my first Tales game. Gotta say, I really enjoyed it and find it hard to believe that the whole series could be seen bad or objectively bad. There was a couple game design issues, like missable sidequests for unique items and costumes that I think is bad, but it sounds like those got remedied in later releases. The combat system is definitely unique and was a nice change of pace of other RPGs I've played. Probably just not for you, but the series as whole seems good to me and a general public
The only bad game I can recall playing all the way through, sort of knowing it was terrible was the PS2 Frogger game:
The game glitches out all the time, NPCs can clip out of existence making parts of the game either impossible to complete, or incredibly easy to complete. The combat doesn't work, a lot of the characters in it are disgusting, and not creatures that are made to look disgusting, the motives for progression are weird, and nothing really feels fluid. Frogger wants to save a princess to become a human.... he fights by spitting and with frog-fu, which doesn't work. The camera is terrible, and I can't think of much if any good there. I don't really know why I finished it, I was a bored kid who just wanted to see how it could end, but I finished it somehow.
Metacritic gave it a 32%, and I think that' a pretty fair score.
