Forrest Gump by a country mile
I can't understand the LOTR love. They are perfectly fine movies (7/10 in my view) but they ARE overly long (is it a hiking movie because people just keep walking and walking), lack plot, have the most wooden characters ever, poor script. They have excellent makeup, costumes, sets and battle scenes but that is not enough to make a great movie. It's like having wonderful garnish but everything else on the plate is kinda tasteless like cardboard.
Forrest Gump is emotionally engaging. Hank is out of this world. It has that true cinematic magic about it. This is why you watch movies. LOTR doesn't have that - you feel like you've just watched another fantasy action movie.
