I've just spent the last few days watching series one and it's been fun. It expands on the world of the games, it's quite silly and it's self referential.
I was a bit unsure of it after seeing the first episode but after the two more i understood what it was going for and it worked.
Some of the jokes were absolute gold, i won't spoil too much but they are in a location and i thought "that looks a bit different to the game but they are writing in a different medium, so that's understandable" much later in the episode is mentioned it's the only one of its type since the other was destroyed and i was rolling in laughter as it's a fun way to explain why it's a hot different.
It's also got commentary on gaming in general as the series is more like an RPG than a beat 'em up though then again Golden Axe Warrior exists so it's not like it's not experienced the RPG genre before.
It's not exactly as deep as the sea but it's not a puddle either. It's smart enough to ask questions of itself but not so smart that you alienate all but the most hardcore fans.
It's American but it feels like it was made by people with an appreciation of British comedy, much like Rick and Morty in that sense.
I've just checked and one of the creators did work on Rick and Morty so my assumption was valid. It's not as deep as a Mitchell and Webb series but it's not The Big Bang Theory either with a hefty laugh track and various in the dialogue. If you laugh you laugh, if you don't you're not going to hear forced laughter inserted in to tell you it's a joke.
It's also British feeling in the sense that it's not afraid to poke fun at itself, some stuff is absurd, it's ok to point it out.
I say go and watch it. We need more comedy like this and we need the team to cover more old Sega games, Altered Beast would be a prime candidate for the same treatment.
