User blog comment:AGuyHere/Best and Worst Version of that Character: Lindsay/@comment-25297892-20150221175716/@comment-25297892-20150222174348

Sadly most of the 1st generation chars became irrelevant after the first three seasons despite their potential and/or missed occasions: Lindsay, Harold, Leshawna, Trent, Geoff, Bridgette, and DJ all fit in this category. There are also Beth, Cody and Justin that got their shots but after that nothing (luckily, but this is my own opinion).

The rest is made of screenhoggers whose destiny was mostly derailment to the point fans got sick of them in 5 seasons: Gwen, Courtney, Duncan, Owen and Heather...

...and underdogs who never got much attention from the Writers being forgotten or recycled as fodders and cameos: Izzy, Eva, Ezekiel, Tyler, Noah, Katie and Sadie.

No surprise they continue to add new characters, unless they pick from the never got opportunity underdogs they can't use the old cast anymore to do something good and original. And let me underline that from the underdogs list only Noah, Izzy and Eva are liked by the fans.
