Okay, we're pretty far in the story here and while it is blatantly obvious that the airplane was carrying a freakin' dream team of red shirts and conveniently classmates super students. Even Mr. lame-ass-gets-the-girl(s) is a true leader who only shows his true power while outmaneuvering dinosaurs (note: there are no dinosaurs, really). Come on, this is totally a set up. My inner geologists (my parents -lol I ate them) are screaming at me and they're not screaming "Take out the garbage!" because that is my bruders job. I'm screaming "Google did it!" at the moment. Sentient Mushroom Head is just stupid enough to trust google maps.
Plot: Like I said, Google did it. Someone compared this to Lord of the Flies? This is almost nothing like Lord of the Flies and nothing to compare it to. Read a book. I think you'll find everything has been done so really good authors just do it well.
Characters: Nice to be able to remember them. I don't care about them, fine if they die, plot moves on. But I do know who they are/were. which is nice. I wish they would show more of the other group with the hot delinquent and his car keys and quarters... that guy is so cool. I wouldn't mind if it was just them but he is a nice foil. And the leader guy for the big group is cool too for once. Which is why HD is needed in the first place. Having him and leader guy together would draw attention away from leader guy but with no hot delinquent, leader guy would have no one to be better than.
Art: I just finished rereading Zippy Ziggy so I'm like "wth with these LAME reactions?!" Although besides everyone seeming to have facial expressions only for varying states of "I'm concerned~" its really nothing to be concerned~ about. A couple times I have thought to myself "lol, boobs don't work that way." On another note, I practically did backflips when the mangaka got their geology right. So easily pleased.
Btw, I'm bad at names so thats why I call maruma/marima/mikaela Sentient Mushroom Head and others other things. Sorry if there is any confusion. If it makes you feel better, I don't know what I'm talking about either.
