Green Day have a huge fanbase. No matter what they do, there are always going to be people who have issues with what they're doing. There are fans who want a return to 90's Green Day, there are fans who want another AI or 21CB, there are fans who want them to make another album like RevRad, there are fans who are perfectly fine with them doing what they're doing now and there are fans who want them to change things up more. It's not hypocrisy that people are complaining about too much change or too little change. These are usually two separate groups making these complaints
I think the RevRad complaint about it being too safe and similar to their previous albums is a valid one even if I do like that album. But my issue with FOAMF isn't that they've changed too much, it's that the quality of the songs is just not at the standard I want. The more experimental or different tracks like Oh Yeah are not tracks that I care for but even some of the more Green Day sounding songs, & even some of the better ones just don't compare to what they've done before imo. I don't want to be too negative about the album because ik it's gotten its fair share of unfounded criticism but it's the album I listen to the least now despite it being their most recent, and I don't listen to their pre-Dookie stuff that often.
I'm not against another Foxboro-esque album if it's at the quality of Stop Drop & Roll, that's a great album that nobody listens to anymore. I'm hoping this new album is going to be a return to form, no matter what it sounds like but the teasers we've got have me intrigued
