Shinya! Tensai Bakabon

Such an underrated show in my opinion. The fact that it has a 5 rating (which I agree with in certain terms) makes me sad, and the fact that almost no one watched it makes me sad as well.

Was this show an amazing show which doesn't deserve the score at all? I would so about 20% no, the other 80% says Yes. The series is legit just dumb fun. It makes meta jokes and constant dirty humor. However I think the show accomplished what it set out to do. To be just plain stupid. Honestly the about of screenshots of the dumb shit the characters ... say in the show is way to much.

Honestly this might just not be your kind of humor and you just might find it annoying, weird, and say to yourself wtf is this then I don't blame you. However I do think this series is something worth giving a try and seeing if you might like it or not, because I tried it and I loved it.

Don't base your commitment to watch the entire series on the unrepresentative first episode: If you came here expecting a spiritual successor to Osomatsu-san, you will be sorely disappointed. Both Shinya Tensai Bakabon and Osomatsu-san may be modern reinterpretations of Fujio Akatsuka's classic works, but Bakabon completely fails to catch Osomatsu's momentum, insultingly incapable of recreating its wit or boldness.

An overwhelming number of skits has the main characters stubbornly resist to come up with jokes or situations where something funny could happen. Instead, they sit around spitballing what they could do this episode, only to reject each other's lazy ideas by saying they'll get in ... trouble with the broadcaster. This would be a little less inexcusable if this was a 10-minute improv format like gdgd Fairies/gd Men. Referential humor is a debatable topic, but even if you like it, you'll get sick and tired of the characters constantly breaking the 4th wall by calling out that they're only tiptoeing around a reference without committing to it. It's as if Family Guy was about to make one of their infamous manatee jokes, but before they can even cut to the unrelated scene, someone interrupts and yells "No we can't do that on tv!". The characters also often address that the show has no budget, that they don't want to animate anything, that their broadcasting station is shit, and that they don't expect people to watch it anyway - and that's usually supposed to be the whole punchline. Similarly, when a famous voice actor shows up, the punchline is always the heavy lampshading of the cameo, and that it serves no other purpose other than having the voice actor on the show at all (paraphrased: "Hello I am indeed THE famous Hiroshi Kamiya, hey wait why is my cameo already over???").
The writers probably couldn't come up with proper comedy situations because they kept the characters from 50 years ago as-is, instead of reinventing them like they did it with the formerly indistinguishable sextuplets from Osomatsu-kun. Worst of all: The two most flanderized characters, Bakabon's Papa and Mr. Policeman, take up the majority of the screen time while (slightly) more versatile characters like Bakabon, Mama and Hajime hardly ever show up at all. Even Eeldog shows up relatively rarely, even though he is the only designated straightman to Bakabon's Papa's stupidity.

In summary, Shinya Tensai Bakabon is an offensively pointless, self-referential comedy about outdated caricatures that relies too much on 4th wall breaking and nostalgia for an era that almost nobody in the Western anime community can relate to.

I started this anime because of it's relation to Osomatsu-san anime, I think you guys can understand by what I mean here. Also, surprisingly I enjoyed it because of the various guests that I recognized. That and the casting (popular actors) that's involved.
However let's cut to the chase here. This anime was a 4/10, maybe at best 5/10 in overall. With such minimum enjoyment, it's something I wouldn't re-watch or recommend at all.

Story - 5.
Being slightly misled by the first episode but that was probably to built some extra atmosphere for the rest. It doesn't keep the same expectation afterwards. Obviously there's really no ... story but just "gags". Only one part had me sincerely laughing which was the "shit" otome visual novel part.

Art/Sound - 5.
Yes, it's neon purple and it's even been simplified to literal 1-D once. It made up for some random CGs / change of pace to "freshen" it up throughout the series. If it was left as it is, this could've been less than a 4.
Forget the music, except the one part that caught me off-guard being "Merry Christmas Mr. Lawrence", very unexpected and pleasant.

Character - 4.
Not much to say, it's just simply gag-repetition per character. [Although I've enjoyed seeing guests being included in the series, a minority does not represent the majority. I would give it a 6 for this though.]

It might not be my cup of tea and definitely not a personal recommendation, I guess it's something you can "try" regardless.
