I largely agree with DolorousStroke. The season was described by the showrunners as a set-up for the entire story, and I still hope and trust that from s2 onward, where they have said it will be more based on the text(s), things will improve.
I also agree with Rob. A lot of the problems people have with the show just didn't bother me. The only thing I was greatly disappointed in was using the callback to Jackson's Gandalf for the Stranger. The mithril healing the leaf was a bit silly, when the show told us (through Elrond) that the Song of the Roots of Hithaeglir was apocryphal (and Gil-galad doesn't deny this!). Most of the things I appreciate are failings are really second-hand opinions from people who I trust know more than me about how tv is supposed to work (since I don't actually watch much at all, of any sort), and who are more picky than me about adaptation.
