" While ' President Evil ' was not a favorite , and has a few annoying moments , it was generally a perfectly adequate episode of Veronica Mars . That is , until the ending .

" Television Without Pity gave the episode a " B- " . 
 Reviewer Alan Sepinwall also had mixed comments , comparing the episode to House and stating , " And yet as much as Veronica was annoying me , as much as I wanted to <unk> at her for automatically jumping to conclusions with Weevil ( more on that in a minute ) , this was maybe my favorite episode of the season . [ … ] Hell , they even had a <unk> ending to the mystery arc for the first time in forever . I dug it . " Price Peterson of TV.com gave a mostly negative review , writing , " This episode was not the best ! Not terrible by any means , but it felt lacking in certain ways , particularly when it came to the total lack of Piz and Dick . Where were they ? Also this episode made it clear that Logan didn 't have all that much to do on the show anymore . "
