Lord of the Rings: The War of the Rohirrim
Animation style and look was great, similar style to Bakshi.
Story, script and language style were mostly nothing like Tolkien would have delivered, and yes, I get it, it's born of a small guiding bit of text from an appendix, but they should have done better.
Pretty much the only reason I watched it to the end is the universe it's set in, if this were a standalone fantasy movie it wouldn't have stayed on longer than 30/40 minutes.
To say I'm disappointed is something of an understatement given I've had this on my watch list for months.
