Both, I think.

Both. But Harry Potter is more likely

LOTR>>>>>>>HP part 2

WTF is LOTR? HP #ALLTHEWAY

LOTR

Harry Potter Pt II was amazing, but the LOTR trilogy is just epic. And The Hobbit is coming

I haven't really read the book for LOTR but the movies affected me to a whole nether level. Everything related to fantasy/medieval genre or book to film adaptations after the Trilogy or specifically, Return of the King, became **** to my eyes or average-looking. I wanted Harry Potter to prove me wrong till the end of the series, but alas it did not. I guess it only make sense as HP can't easily be adapted to a movie with the length of the books. I still remain with the thinking that series is most iconic during Philosopher's Stone. It's probably the only film of the series that could actually go on becoming a classic. I still love the last film but it cannot top Prisoner of Azkaban/Goblet of Fire if we're talking about artistry and being cohesive all around in terms of plot or direction. There's just something about the latter half of the series being unsatisfactorily IMO.

Who is LOTR?
Harry Rulez!

Lord Of The Rings.

Rio.

Harry Potter will end up being more remembered than LOTR for sure.

I can't stand watching one of the LOTR movies without falling asleep halfway through it.
They're all epic though.

But please... Harry Potter >>> deal.

This. I don't know why but Goblette of Fire was the last one I was actually impressed by.

Harry Potter of course.

I hope it becomes the highest grossing movie of all time

Deathly Hollows Pt 2

Please, many people already don't remember LOTR.
HP>>>>>

LOTR is already a classic.

LOTR is a CLASSIC.

I am a HP fan, but the whole LOTR trilogy is critically worshipped, while the only HP to get really strong reviews is the 8th, so LOTR probably be more lasting in terms of that arena.

However, both made billions, so I think both will be at least still highly watched for years to come.
