He is watching LOTR for the first time
Nice! My kids haven't watched LOTR either because I was waiting until they were old enough to see them on the big screen since a local Minneapolis theater has shown all three EE's every December for the past five years. Until this year COVID happened.
(First world COVID problems compared to what your family is experiencing of course.)
I now view LOTR trilogy as a replacement for The Ten Commandments and Ben Hur holiday viewing tradition.
I know people don't much care for the Hobbit films in these parts but holy crap is the PQ of those movies on 4K awesome. Probably the best looking movies I've ever seen at home.
