Right, giant robots. Gotta love 'em. Trouble is that the genre can get a little played out. Which brings us to "Planzet." Ok, it's CGI instead of usual anime animation, that's a little different. Unfortunately, what's being animated is pretty lifeless.
Speaking of lifeless how about our Earth. Generic Aliens with ships like starfish/throwing stars have basically slaughtered 90% of humanity and are working to better their score. So what's our reaction? Find three of the most unlikely people to be professional soldiers, stick them in super robots and then have them hold off the invasion as we power up our alien killin' cannon. One of these soldiers is our hero who was a slacker pre invasion but now wants to avenge his father and defend his sister. It's good to have goals.
Unfortunately they fail, luckily there's a fall back plan.
And so it goes. Really there's is absolutely nothing new here. There are some nice shots to be sure, I like where the alien space ship/moon eclipses our own. But even the great animation is iin trouble. It has a rushed feel to the whole thing. It's like being in an expensive restuarant to only have the waiter behind your back the whole time.
If you like giant robots it's and ok watch just don't expect too much out of the experience.
