Yep, I somehow got myself roped into a twelve-hour Tengen Toppa Gurren Lagann marathon by a bunch of friends. (This was actually a while ago, but I didn't get to update, so yeah.)

...AWESOMEST THING EVAR.

See, I'm normally very logical. This wouldn't be a problem, except the logic part of my brain refuses to shut up. Especially during movies. Therefore, I have this issue where I am normally incapable of enjoying any sci-fi, fantasy, or what have you because my brain is too busy picking holes in the logic and science. For instance, the glider thing in the Dark Knight. (I had to be dragged to see that one.) Also the entirety of Jurassic Park, which I was also forced into watching. Seriously. Cloning doesn't work that way. And WTF was with the random explanation involving frog DNA causing the sex-changing? First, dinosaurs are reptiles. Frogs are amphibians. And even ignoring that, unless the sex-change bit is in the mitochondrial DNA...
See what I mean?

The only way to get around this is to either have the (pseudo)science be very well-done and convincing (rarely happens) or to have it be so damn crazy that it pretty much crashes the logic part of my brain. Or to be so stupid that it doesn't even register as science *coughStarCrashcough*, but that's another story. Three guesses as to which category Gurren Lagann falls into, and the first two don't count.
I still managed to hold on until about episode 15 (wailing about butchered physics the entire way- made even worse because they make a point of adding nods to reality here and there), but the final battle (of the first arc!) was just too much. I'm told the look on my face as my brain crashed due to an entire apparently levitating, fricking enormous structure (spoiler alert, won't specify) turned into a GIANT F***ING ROBOT was highly entertaining. After that, I just kind of went with it and prayed that my brain wouldn't ever catch up. And cheerfully enjoyed the entire hilarious recap episode before rushing into the second arc. For the record, this is one of about three things total that have ever managed to do this.

GO WATCH THIS THING RIGHT NOW, PEOPLE. For those of you who haven't yet seen it, a quote from TVtropes: "How big can the robots get? How manly can the heroes get? How epic can the sunglasses get? How enormous can the drills become? How excessive can the explosions get? How awesome can the Heroic Sacrifices get?... The answer to this question for Gurren Lagann is always 'About 80 times bigger than the one you just saw.'" Case in point: throwing GALAXIES like shurikens. HOLY SHIT. It starts out absolutely insane, and outdoes itself every single episode. The marathon ended with every single person, including the normally shy, overly logical or quiet types, bellowing out the closing theme at the top of their lungs. At well past eleven PM.

It's the kind of thing that makes you want to charge out roaring and kick ass. (Hot-Blooded, physics-defying Gurren-dan!Nekomata. OH SHI-)

Have a nice day.
