I mean first of all transforming King Arthur into a needy kind of female servant of a Japanese guy that is tethered to him and must obey his commands...............

I'll just let that one sink in for a bit.
Anyway, moving on now to be objective completely, Saber actually does have sort of an interesting personality, the idea of King Arthur repenting for some sort of failure clashes with the idea of King Arthur as this kind of indominatable super king (I read a fair amount of King Arthur legends once upon a time), but it's not an entirely inconsistent switch, given his issues with Mordred and Lancelot and Guinevere.
Can't say the gender bending bothers at all, why not a female King Arthur? Or as the show states, Arturia.
No the problems become clear really once we start moving a bit outside of Saber, and what do we have? I don't even know what we have, to be honest, it's hard to remember who was what or why, particularly in UBW.
Basically Hercules is a monster from a video game, Lancer is some kind of baity edgelord, and then you have a smart but shy girl... which.... pretty sure.... encountered that one.... somewhere.
The rest, are there more? Can't say, the point is once you move outside Saber they just were basically mobs in a video game. In fact, most moments are filled with just very long and built up fights.
Sorry but, might as well just play a video game.
