I first heard about "Nirvana the Band" a few months back and while it seemed somewhat interesting, its sort of bland look kept me from checking it out. Now that I've come through and watched all episodes, I have to say that I never laughed so hard at any show in the last 1 or 2 years.
For me, the lack of flashy presentation and stylized look turns out to actually not be a shortcoming but something that really helps to sell the humor the show is going for. Somehow, the low-fi aesthetic makes it feel more authentic and really facilitates the seamless blend of scripted scenes and "prank" like improvisation that's going on all the time. If you look closer at how the episodes are put together, you begin to realize that this "homemade" quality is an aesthetic choice and the editing and planing that has to go into creating it must be enormous. But the hard work pays off 100%.
The biggest compliment I can give "Nirvana The Band" is that its style of comedy at the moment feels completely fresh, like nothing I've ever seen before. And -most importantly- it feels not only "new", it also really works. The guys embody their characters so completely that nothing ever feels "acted" and the ideas that drive the "plot" are so surreal and insane that I cannot even begin to imagine how they manage to come up with them.
This is the best new show I've discovered in 2017 so far, I really hope that it eventually gets the audience it deserves! My guess as to why it has been mostly overlooked, is not that it is "too weird" (Compared with, for example, something like the Eric Andre Show), but rather that it sort of defies the comedic fashions and stylistic devices of the time. It's completely its own thing- which sounds vague and meaningless, but if you've watched it you'll certainly see what I mean!
