The early 2000's like ethereal watery aesthetic is such a vibe 
and Tidus' outfit is so loud I love it, peak Tetsuya Nomura.
Also I got the game to run full speed on my potato in PCSX2, a pro-tip enable multi threading and direct 3D 11 in the emulation and graphics options.
PCSX2 actually makes a lot of games look considerably better than they did on the PS2 because of the interlacing the original hardware did. This video is a good comparison: https://youtu.be/eedxkq-Ctpk?t=651
But yeah the style of this game wasn't bad. I feel like almost the entire world was in an overcast eternal sunset which felt mildly depressing to me but contrasted nicely with the incredibly positive over-acting way everyone puts on a brave face because of the circumstances. The whole group dynamic reminds me a lot of the way groups of people deal with terminal illness.
