The ending was the most WTF thing I've ever seen, but I actually liked it. This is one of the few mangas that left me with my mouth wide open, honestly I'm not lying. WTF LOL

Someone recommended that I read this oneshot, so I did. This freaking story is one of the weirdest things that I've ever read. For the first time in my life, I have no idea what else to say. Read it for a good laugh, or (like many others before me have said) for the sheer "wtf?" factor.

I thought this was an incredible oneshot! It was weird and just flat crazy, but it had some really interesting characters. I HIGHLY recommend reading this at least once. The whole last third is AWESOME!

Nice little oneshot here about Ralp the T-Rex who gets thrown in the future and into a teenage girls body. Where hillarity ensures, due to going from RALPH SMASH, to beeing a week teenage girl. Wierd ass plot though.

It did feel a bit rushed, and Is this really from 2005? The art feels like it's from the 80's, and the art gets messy sometimes. Still it's not bad, I liked it. Well worth reading imo.

A brilliant comedy with social commentary undertones (I won't spoil them, but it is outstanding), The only flaw is that the art gets weird at some points.

Yes, there's abit of wackiness here. Still, it's logical in its way, and quite clear from start to finish

Its shortcomings came from its jerkiness of plotlines, scenes and lack of details. It was an old manga after all. With its kinds of ideas, if it's done nowaday they can draw it out to at least 3 vols. As it is, one is just too short. Hence the 8.

The idea about dinosaurs was interesting and a bit funny.
But how in the world became the great macho dino king T-Rex such a romantic lovebirdy? It simply dosn't fit? Was he gay?

Yes. This manga does give you that "wtf" look on your face as you read though it. Lol. ^^ Like akurashy said, the story did make sense, despite the weirdness here and there. Still, I enjoyed it and it made me laugh all the way though. bigrazz
