Sidequest complaints for specific games generally confuse me because
Every sidequest in every game is either a fetch quest, a 'go here kill things' quest, or a shitty minigame
If you don't like them, skip them
There are very rare exceptions with games that try to shake things up (only ones I can think of are Majora's Mask and maybe Skies of Arcadia) but overall sidequests are inherently uninteresting, especially in JRPGs. They're there to pad game time. If you're enjoying the core gameplay loop, you might enjoy the side quests because they amount to 'more game'. Otherwise...don't do them and play the main story?
