Pacific Rim.
The giant robots spend 95% of their time punching the giant aliens, but at no point in the entire movie does a punch accomplish anything at all. Effective weapons for killing kaiju exist. The hand laser cannon on the mech toward the beginning is a 1 shot kill. Put about 10 of those on each robot. Or, wait until they get to shore, then truck in a cannon. There are other ways to kill the kaiju of course. But punching is not one of them.
Let's borrow a phrase from another science fiction monster movie, "Nuke it from orbit, it's the only way to be sure."
For the money they spent on Jaegers, humanity could have built a handful of space based missile or laser systems, parked them over known spawning areas, and just zapped them as they came through.
