When you do make sure you see the extended editions.
Nah, see standard first if you're not a hardcore fan. The pacing is more natural. Then, next time, see the extended editions.
I remember LOTR fondly from back when it came out. It was an event. All us nerds were high on it for months.
But I saw a fragment recently, playing on some cable tv or something. It was kinda shit by today's standards. The CGI is shit. The acting is hammy. It all feels terribly quaint.
I will fight you

The LotR movies are peak cinematic experience. The music and cinematography was astounding, and the CGI is much better than some modern examples I could name - and works mainly because it's used so sparingly. Make-up was more common than CGI by far.
I can watch LotR time after time and still
feel its emotional message. And that's an entire trilogy. I can't do the same for any other modern film I could name.
As for hammy acting.... I don't understand how you get that at all. The worst is Frodo, but even then the acting's acceptable. Every other actor played their character so well that they
are those characters. When I think Gandalf, I see Ian.
