There are plenty of good Weezer songs post-pinkerton just not as many good albums in whole. Green to me is still one of their best and I like it in full but after that it is a mixed bag. Really not a fan of Raditude or Red but even those 2 albums have at least 1 song I actually enjoy. Perfect Situation from Make Believe is also one of their best songs if I was to judge. Despite the comical nature of Beverly Hills as the opener to that album Make Believe is probably my 4th favorite. Hurley is pretty good but I would not go as far to say solid overall.
Yeah I'd agree with all that, though I do find myself listening to Maladroit a lot more than all of them. I think that's their most solid album post-Pinkerton.
