Seeing how they are portraying the relation between Elendil and Isildur really provides depth
into who Isildur was and why he ended up doing what he finally did.
The characters in the show have very little to do with their namesakes and besides that, RoP's Elendil is a plank of wood (until this last episode when he becomes a tearful plank of wood) and Isildur is an idiot so I'm bemused as to how you reckon that.
So, if you havent watched it because of bad online reviews: do yourself
a favor, watch it and form your own opinion.
Well, I already have and as far as I'm concerned, the negative online reviews are in the right and the only reason to watch it is out of morbid curiosity. I can't recommend it to anyone otherwise, it's just that bad. Not just as a Tolkien adaptation but as fantasy, period.
