Honestly, this is a valid complaint.
Now, keep in mind this is coming from someone who actually for some reason enjoys FF7's graphics.
Bad graphics for the ps1? Not really, but they are bad graphics. FF7 was made to show off fancy new graphics, and there is a risk/downside to that... we really didnt have 3d models down at all back then, and that shows. As such FF7 did not age well in the graphical department compared to say the old sprite-based games. For every decision there are pros and cons, and the decision to make FF7 graphically the way it was is no exception. It was fantastic for its time, but its not its time anymore.
Now, remember, I do love FF VII's graphics and find them quite charming... but complaining about the graphics is definitely valid. Maybe some complaints about them arent, but that doesnt make the ones that are any less relevant.
