Hard to rank them, as I like them all besides the lowest ranked one on this list, but probably something like this:
3. Make Believe - extremely underrated
5. Raditude - not nearly as bad as a lot of people think it is
6. Hurley - this may go up after repeated listenings, as it is very solid
8. Red - a complete mess. only 3 decent songs.
Blue.... will always be #1
Weezer has changed a bit over the years, but if you listen to the albums straight through, Hurley belongs just after the core 4. Green and Maladroit catch a lot of crap sometimes, but they both have the true Weezer sound that I love and that has been missing... until Hurley.
