Sometimes, you just want to read something that will make you happy without requiring much of you. Examples that come to mind:
Gon seems like it should be the exception here. It's rated T for violence (and recreational mushroom use in volume 4, which nearly had me needing my inhaler, I was laughing so hard) because it's about the natural world, sort of, so things get killed and eaten with appalling regularity.
Gon is kind of offbeat, anyway. It's a manga with no words where each chapter has a different cast of animals except for the titular main character Gon. Everything is drawn meticulously, including the chief anachronism: Gon is a baby T-Rex.
Gon interacts with (often by bullying) other creatures in sometimes natural, sometimes bizarre ways. He's a simple creature: give him food and a place to sleep, and he is one happy camper. Some chapters consist of him searching for food, finding it, and eating it with the hugest look of contentment on his scaly little face.
In others, he self-importantly bullies other bullies or lesser creatures or whatever he feels like bullying that day. (I protest at his treatment of those dingoes, but the look in his eye as they turned up their noses at the food he offered them at the end almost made up for it.) How can so much be portrayed using only the facial expressions of animals? It's sort of genius.
Sometimes the laughs are unintentional because some of the animals are a bit too reminiscent of Tezuka's, but there is something out-and-out hilarious about the looks the artist draws in the eyes of, say, the fish Gon catches and is about to eat (flashbacks to ZatchBell there :), or the animals dying or having bad trips after the great mushroom march in volume 3. It's priceless.
Kudos to CMX for publishing this little gem. It makes me laugh and cry in a much more free way than I usually can while reading manga. I shouldn't be this relaxed after reading about the law of the jungle in action or subverted, but something about Gon makes it okay to just read, experience, maybe cry a bit, and move on.
Any favorite decompression manga/anime you have? The thing you go to read/watch when you've had a bad day and just need to unwind? Is it a specific genre or just a specific title or two? Why do you think they have that effect on you?
