<P> The growing tensions between Rick Grimes and Shane Walsh have been well received by television critics . In a review for "Bloodletting", Joe Oesterle of Mania.com commended the performances of Lincoln and Bernthal . Oesterle wrote, "Andrew Lincoln and Jon Bernthal (...) gave a fine bit of acting, and I found it interesting how the character Rick started looking and walking a little bit zombish after giving blood . The scenes between the two men were moving, and if you listened close you could decipher the main differences between these two cowboy cops . Rick is bound and determined to get back to his wife and let her know their son is in mortal danger, without ever doubting his own ability to successfully complete the mission, while Shane on the other hand is not quite as automatically selfless and heroic ." </P> <P> Several critics lauded Grimes' interactions with Walsh in "18 Miles Out ." Writing for CNN, Henry Hanks said that "Rick made it clear to Shane that he had to respect his rules from now on ." Alex Crumb of The Faster Times evaluated their physical confrontation as "wholly satisfying," while Entertainment Weekly writer Darren Franich appreciated the fight scene involving Grimes and Walsh; "The Shane / Rick fight was great, a brilliantly extended scuffle that started out with an air of boys - will - be-boys pettiness but quickly escalated into something genuinely homicidal ." Berriman of SFX summated: "It's shocking when Shane hurls a wrench at Rick's head, but even more shocking that Rick is prepared to cut and run and leave him for dead . Rick's change of heart when he looks down at the two dead walkers on the floor and is reminded of the friendship between himself and his former partner is a beautifully played moment, which speaks volumes without a single line of dialogue being uttered . The fact that, come the end, he's willing to trust Shane again after all that has gone on between them is genuinely touching ." </P> <P> By the start of season three, Rick's character arc developed him into a more world - weary, cynical, ruthless, and hardened person . Erik Kain of Forbes said that Rick started out as "the voice of reason, a calm presence, and an earnest leader" in the first two seasons, but had developed into an "anti-hero" by season three . Tom Ward of Esquire noted that Rick was almost a completely different man by the end of the fifth season: "He may resemble the clean - cut law enforcer from the first season, but inside,' stuff' and' things' have changed the man with the highest zombie kill count in history...Has Rick become the show's villain? After Rick and his group slaughtered the members of Terminus, Andrew Lincoln voiced that "(i) n Seasons 1, 2, and 3, and half of 4, Rick was a man either restraining or denying a brutal part of his personality, in order that his children grow up and, hopefully, have a father that was morally sound . A father who could give a good value system to his children . The difference in (Season five) is that there is no safe haven ." </P> <P> In the seventh season, Zack Handlen for The A.V. Club was critical of the morality of Rick and Tara raiding Oceanside . He assessed, "...we are forcibly reminded of The Walking Dead's greatest weakness: Rick Must Always Be Right (except when he's trying to fight against his destiny as a leader). The people of Oceanside almost immediately lose what little distinctive identity they once had, falling in line like they were just waiting for some bearded dude to show up and start ordering them around, and there's no acknowledgement of the weirdness of this, of how close Rick's tactics are to the very man he's trying to destroy". </P>
