The following actors (in alphabetical order) are all good, solid performers who work in their roles, they just don't stand out outrageously like the above four do for me. They DO stand out among the other actors who aren't in the above or below categories, however. (Especially Brad Leland.)
The Not So Great
It truly does boggle my mind that the casting of this show could have hit the bulls-eye with four of their actors and come close enough with a few others, but completely miss the shot in not one or two, but three other cases. Tyra is one thing, she's not a huge character, but Lyla is and her off-casting is just not good for the show at all, and with Smash's growing storyline the lack of sympathy that Charles is generating is hurting that aspect of FNL as well. This is a great show, but they really fumbled the ball in some of their casting choices. Because of the above three (especially Minka Kelly and Gaius Charles), Friday Night Lights is not one of my MUSTWATCHNOWSHOWS!, and sadly, I do think it would be were the casting not so wrong in these cases. It's a shame.
