I really liked Benediction, about war poets Siegfried Sassoon and Wilfred Owen. While I wasn't a big fan of their stuff at school (where we studied their poems for what felt like years at a time, and in as uninspiring a way as is possible), as an adult I can recognise the greatness in their work, and it's a really enjoyable and entertaining film. It focuses mainly on the life of Sassoon, and it really had me hooked for its 2 and a quarter hours; Jack Lowden (from Dunkirk) is very good in the main role. It reminded me to hunt out Regeneration, a film I haven't seen in years but thought was great at the time, as that would make a good double bill with this.
