Best: Alvin Olinsky
In terms of upholding the law, Alvin Olinksy (Elias Koteas) is not a role model. He performs lots of questionable acts during his time on the show, but the fact that he does so with the intention of exacting justice makes him a complicated, oftentimes thought-provoking character.
His friendship with Voight is one of the best in the entire show. It really felt like these two guys had been through a lot together, and had respected the tough decisions that the other had to make to get by in the Windy City. Olinsky’s death in prison hit Voight harder than arguably any other death on the show, and we have to admit: we get it.
Worst: Kenny Rixton
Fans don’t have much to say about Kenny Rixton (Nick Wechsler) in retrospect, and that kind of sums up the problem with his character. He’s just there. He’s brought in to replace Ruzek (Patrick John Flueger) in season 4, and blends in decently well with the rest of the IU. Given how he looks and how he carries himself, though, it’s hard to shake the notion that Rixton is just a poor man’s Ruzek.
He doesn’t get a lot of time to distinguish himself throughout the season, and he leaves without making much of an impact on the overall season. Rixton is an example of a placeholder character at its worst, and yeah… we aren’t holding our breath for a surprise return anytime soon.
