I loved the tv series. Seasons 1 to 3 in particular I've probably seen at least 4 to 5 times each. However if you're here for a laugh you won't find it in this. It's just the "lore" of the doomstar and anything else which I feel was better when it was in the background. I'll admit this was WAY better than the "musical" ego trip they put together but this is still not very good. Maybe a die hard fan who has no sense of humor will love it. At least this was better than the Aqua Teen Hunger Force movie that came out recently.
I liked it better when the series was about out of touch rockstars. Getting plastic surgery, why it's dangerous to date fans or trying to get back to their roots are three that come to mind. The episodes were mostly short but because of that we craved more. Compare that to the 4th season of The Twilight Zone where the episodes doubled in length and some of them were extremely difficult to get through.
The art style was very hit or miss. The final battle was trash. This was a great idea on paper but perhaps it was the best they could do with their budget. I found myself constantly getting bored as the story struggled to keep me involved. I love how spiteful Nathan is to the fans telling them where to go in the beginning too. This is full of boring cliches and I didn't enjoy it at all to the point I wish this was never made.
Either way. If there is little to no humor and just the "lore" it honestly that's like if half the band didn't show up to play a concert. Yeahhh pickles and toki showed up!
