The thing was, Legolas's fighting in Helms deep was still relatively realistic, he used his bow a lot and any swordfighting action was human paced and generally performed with two feet firmly on the ground.Sniper Team 4 said:You forget, the elves were getting stomped into the ground before those two showed up. And at Helm's Deep, the elves got downright slaughtered. Did you see any of them standing after the battle was over except for Leagolas?
We all remember *that* shield slide down the Helms Deep stairs because that was the most flashy, acrobatic action that Legolas performed in that battle, and it was enough to cement him as a badass because of its difficulty to perform while still being perceptively possible for a human to manage, but Legolas nails it in one go.
In the Hobbit 2 he does the same sliding on an object what... 3 or 4 times? but we barely even realise it because it's wedged in between his triple somersaults, random flips, superfast swordsmanship ability and balancing on heads while all around him Elves and Dwarves cut down enemies at triple speed with moves more suited to figure skaters than warriors. There are no defining impressive feat moments like the stair sliding, because it's just a constant stream of impossible skill.
The fight scenes have lost their human relatability, as we are watching these warriors jump about and casually perform impossible feats. In the LOTR movies Legolas and Gimli fought like an incredibly highly skilled human. Their weapons moved at the same speed as mens, their acrobatics were conceivably possible by a trained man (up until the Pelenor fields Oliphants scenes anyway), they fought and moved with limits.
In the Hobbit they fight like Neo from the Matrix. They fight impossibly fast, hit impossibly hard, jump impossibly far repeatedly and it just means the weight of the combat has been lost as we move from highly competent to cartoonishly competent.
