Pretty sure it's not the pop element that people don't like. Weezer has always been extremely poppy. It's the lazy/bad songwriting that kills it for me. "We Are All On Drugs", that Lil Wayne song, etc? Ugh. Those are really the only two records I don't care for though.
Those two songs are awful and to go along with Beverly Hills its just bad but Make Believe had some good songs like Perfect Situation, Hold Me and Raditude had some good songs like Trippin Down The Freeway, If your wondering If I want you to, let it all hang out, I don't want to let you go etc
