Without having seen the series I’m guessing yours is probably the most accurate descriptor I’ve seen so far.
Whenever it comes to fandoms like this, the camps are always so divided in extremes. And neither camp is usually correct.
I mean, I saw Twisted Metal season 1 and it was not good by means an “actual reviewer” would stand by. But was it enjoyable? Sure. (Probably more so if I was high while watching it.) Will it be remembered? Not by a long shot.
The Fallout TV Show is likely better than TM, but I doubt it will remembered alongside Breaking Bad, The Sopranos or even Futurama for that matter.
