I really don't think it's exaggerating- if people think that FFX-2 is the worst one, that's for them to decide, just like you decided that FFV is the worst FF game. Personally, I don't think you're right either- I quite liked FFV. But that's because I'm not you and we have different perspectives.
I think it's worth getting to add to a FF collection, and although I don't think it's the best FF game, it's OK if you don't want anything taxing- it's bubblegum, basically.
if you wanna beat it 100% don't get it.
