Personally I enjoyed this show. Sometimes the premise of each episode can be a lot to take in, but usually by the end of the episode I get it.
It does seem to borrow heavily from some British shows like the Mighty Boosh and Doctor Who. Two friends going on surreal adventures (with not a big special effects budget) with the occasional musical interlude and recurring side characters definitely reminds me of the Mighty Boosh. I can somehow imagine Howard and Vince doing much of this. The Doctor Who influence is kind of the blue box that's bigger on the inside taking people to new places, and the end credits looks almost exactly like the Doctor Who end credits.
And of course, the parallel to Sliders is pretty clear, people sliding between parallel universes trying to get back (which itself is like Quantum Leap).
While it reminds me of those three elements, it still feels like its own show, with the tone being distinct enough to set out on its own.
I can see how this would be weird for some, as it gets pretty random, surreal, and silly, but it you enjoy those semi-non-sequitur, quasi-random British comedy shows, this might be up your alley.
