Fr/Lg was a bit..Blegh. Of course, when you compare it to Hg/Ss, it seems quite...Horrible. But I liked the graphic change, and I like looking at my Pokemon with better color. Personally, I dont give a Pikachus tail about the music, since I usually listen to other music while playing Pokemon (No, im not donwplaying the Pokemon franchises music, its actually quite good, im just not that into instrumental since I like to sing along D:). The way I see it, its like putting your toe into a pool to test and see if its cold or warm. Thats what GameFreak was doing, they were testing the water. They wanted to see the reviews of a remake of an old game, especially the first ones, the ones that were the vangaurd of the Pokemon franchise. They also wanted to see if it would work, if people would like the graphics change and if people who played the old ones would like remakes, and for new players as well.
Since they didnt know exactly what to do, they pretty much just took the old game and gave it better graphics.
But, when you compare HG/SS to Fr/Lg, of course you would hate on Fr/Lg and love HG/SS, because of the endgame being so much more...More. But hey, I like both, and if Fr/Lg kick started the remakes, then I wont be one to diss them XD.
