I don't think it's an unpopular opinion. X is very popular (there's a reason there's so much sequel material for it). I just find the Zanarkand stuff to be a real lead weight on the story, and the emotional heft of the story requires you to care about Tidus, which I absolutely do not.

X-2 is silly but I at least sympathized with the characters. The entire party in X could be eaten by Sin for all I care.
