NOKW - Pacific Rim

Here comes the next chapter in our "I'm Okay With, I'm Not Okay With" series where I point out things in a movie I can tolerate and then one thing I just couldn't (if you want, click here for all of the past posts):

Movie:  Pacific Rim

Basic Plot:  Giant robots fight giant monsters.  Enough said.

I'm Okay With:  The fact that building giant robots was humanity's first thought when it came to defeating giant monsters.  The fact that this movie wasn't that bad except for the fact that nothing happens for an hour between awesome fight scenes.  The fact that anyone lives anywhere near the Pacific Rim when a new giant monster shows up every few weeks to destroy a city.  The fact that the whole two pilot/mind-melding thing still doesn't make sense.  The fact that the robot pilots are all supposed to be really good fighters when their robots can't do anything remotely close to their fighting style.  The fact that I don't understand how the humans can put the monsters into categories as soon as they come out of The Breach.  The fact that the bad guys can so easily keep creating their giant monsters when something that size would take decades to grow, hell, they even point out that the giant monsters can get pregnant.  The fact that the giant robots seem to be too easily defeated and have too many weak spots.  The fact that the giant robots' cockpits can be knocked around so easily which has to make it impossible to fight a giant monster when it is constantly knocking them around.  The fact that the giant robots were flown around by helicopters and yet heavy enough to do battle with giant monsters.  The fact that if a giant robot picked up a large boat to use as a weapon, that boat would snap in half before the robot even tried to swing it, even though it did look really cool.  The fact that I love Charlie Day (of It's Always Sunny fame), but he was terrible in this movie.  The fact that I can't figure out why the first giant monsters didn't come equipped with acid spit and EMP.  The fact that the humans didn't just dump millions of tons of concrete on top of The Breach and block the bad guys from ever getting through.

I'm Not Okay With:  The fact that it would be way more cost effective to just build a bunch of giant weapons to blow up the giant monsters than it would be to build giant robots that carry giant weapons anyways.  It never crossed their minds that building a bunch of plasma cannons every few miles along the coast would be cheaper and way more effective than building giant robots?  Seriously, it pisses me off even more that the giant robots would even engage the giant monsters in combat when they generally just shoot the things anyways.  Why not just stand back and shoot it from afar?  And if you are going to do that, why build giant robots in the first place?  Nothing about the humans "Giant Robot" project makes any sense other than to create a cool concept for a movie.  I am not okay with that.

"And if your giant robot has a giant sword, why not just wield it at the beginning of the fight?"
