We have our first repeat!
I would agree that The Two Towers is probably my least favorite of the trilogy. The epic battles (like the Helms Deep throwdown that seems to take a majority of the last four hours of TTT), while enjoyable, aren't the reason I like the Lord of the Rings movies. Not that those parts aren't good in their own way, they're just not as interesting to me as the overall quest to destroy the ring.
Luckily, while Two Towers had the most human on orc aggression, it also had its fair share of memorable scenes.
