This show plays like some semi-toxic concoction of sugar, speed, and caffeine. I imagine it will produce some adverse reactions in most, hence the low score.
You'll either be laughing from the sheer speed and absurdity that is crammed into every second of each 2~ minute episode, or your eyes will be narrowing as you exclaim "What is this I don't even...." while logging on to MAL in order to justly rate Teekyuu lower than every garbage harem anime.
On the other hand if you are capable of enjoying the ludicrous insanity (or keeping up with the subs), Teekyuu certainly doesn't have any shortage of it.
However, I wouldn't recommend watching it all at once, assuming this review sticks, because you're liable to either:
A) Have a seizure.
B) Get hands/face stuck in the Jackie Chan meme position.
C) Contract Spongiform Encephalopathy, as this show exudes infectious prions.
And yes, that is predominantly why I wanted to write this review.
