After TH, you should be immune to worrying (and the reference to a "young
Galadriel" above should have driven the final nail on the coffin of anyone's "canon" hopes).
I may have mentioned here on TTF in another thread that I saw "Fellowship" in the cinema twice with the space of less that half a week in January 2002 (none of this standing in endless lines for the chance of a "premiere" for me). After the first viewing I basically only had this huge list in my mind about thing where PJ had gotten things wrong. The second time around I viewed the film pretty much with the attitude "some names and
places and
events have been heisted from the book, but that's about it." Had I gone into "TTT" and "RoTK" with my attitude for the first viewing of "Fellowship", I would probably have left at the intermission at the latest.
I didn't know the term at the time, but they're "fanfics". With the usual Hollywood modus operandi of adding irrelevant filling to make them fit their brain-dead cookie cutter better.
With TH, especially after announcing that this would also become a "trilogy", it was clear to me that the fanfic plus Hollywood garbage aspect would increase immensely.
Interestingly, while with the LoTR series showed an increase in film length (in EEs at least) with a serious spike upwards in cinema and EE versions for the finale, TH showed exactly the opposite trend. In both versions the finale was the shortest.
So now we arrive at Amazon. From LoTR to TH, the amount of canon source material shrank dramatically. For the
Second Age, the shrinkage is at least as dramatic. By some strict defenitions, there is
nothing canon about it besides the relevant RoTK appendices. So … "let's do a GoT clone here, those junkies with massive withdrawal symptoms are just salivating for another fix!" could very well be the rallying cry for Amazon. Everything is becoming a soap opera / telenovela, it seems ...
