Cute Cute Adventure? you think. Cute Cute Adventure! I say. Not often have I been able to make a review that is longer than the thing being reviewed. But today I can gladly triumph at my victory. Being at least no longer than 12 minutes, this is probably the shortest OVA I have ever watched. Can this OVA be viewed as a stand-alone? Hardly, you definitely need to have watched Full Moon wo Sagashite to even begin to understand the content and the events in Cute Cute Adventure. If you're reading about this OVA without having seen Full Moon wo Sagashite you're in the wrong place. Beginwith watching Full Moon wo Sagashite (which is highly recommended may I add) before you even consider watching this OVA.
Having said all of this, let's get down to the meat. For an OVA, and for Full Moon wo Sagashite in particular - the story is indeed quite below poor. Taking into consideration that the OVA is under 12 minutes however it is easy to conclude that a magnificent story wasn't on the directors' minds when they made it. The OVA is made for more character screen-time alone, and probably not even in the slightest anything else. Actually, which should also be noted, the title makes a good summarization of the contents - kawaii kawaii Adventure. It's cute, and I reckon some of those who have watched Full Moon wo Sagashite will appreciate that.
The art is like that of Full Moon wo Sagashite, no complaints at all (I can't give a 10-minute OVA a score over 5 though). It's enjoyable.
The sound is, oh, I don't remember if it was the same as the original Full Moon wo Sagashite - but surely it wasn't bad. You won't be able to hear much song variation in a 10-minute clip though, so it never really matters.
Overall, it's enjoyable enough. I wouldn't necessarily recommend it (notice that 3 rate) but to those who find Meroko and Takuto and Mitsuki cute in whatever "adventure" they're thrown into I can imagine that watching this OVA will be an enjoyable ride. For those who never really fancied the humour and "kawaiiness" of Full Moon wo Sagashite (no matter if you enjoyed the anime as a whole or not) could still watch this OVA. It's horrible I said? Well, that's true, but it's under 12 minutes so finding an excuse for not watching the OVA will be difficult enough. At least afterwards you can mark all spin-offs derived from Full Moon wo Sagashite off.
