Here's a short and pointless review, but Teekyuu is also short and pointless so it should fit.
It hurts to try to follow along with Teekyuu, let alone think about it on any critical level. The jokes fly by at supersonic speeds and the actual quality of the humor fluctuates dramatically on a second-by-second basis. Having watched through all 7 seasons of Teekyuu thus far, I've learned to just accept it for what it is, but to make it this far you'll have to train your brain to turn itself off, and your mileage may vary depending on how much condensed randomness you can physically absorb.
That said, this season was probably the most consistent of them all so far - I was able to enjoy every episode on some level, and some of the best moments of the entire series happened this season. Currently I haven't heard anything about an 8th season being announced, but if it gets made, you can bet I'll be watching it. Teekyuu is the kind of anime that I can't drop any more, I've invested too much of my mental well-being into this series to back out now.
I recommend that everyone at least watch one episode of Teekyuu, preferably from this season because like I said, it's the most consistently enjoyable one so far. You'll know right away if you will be able to watch any more of it, but it might take some time before you know if you like it or not.
Upon further reflection, it might not be that Teekyuu is improving, but rather that it has broken me completely by this point. As this is actually quite likely, please disregard everything I've said up until this point. 10/10read more
