> People love Gandalf, Aragorn, Galadriel, Legolas etc. and want to see more of them.
> People don't give a crap if any new story is "faithful".
These two statements contradict. The net effect of it not being faithful, is that it doesn't feel like the Aragorn, Legolas, Galadriel etc. you knew. The casual fans will notice too, just a little later and maybe less consciously than the more dedicated fans.
No. People love an old wizard in grey clothing. They don't give a crap if some lore said he beat 1 Balrog but in the show it was 5 giant orcs or whatever. Casuals have never read the background material, I just want to be entertained.
