Code Lyoko

Season 1 is mostly mind-numbingly repetitive monster-of-the-week filler except for the last two episodes, season 2 starts of interesting then becomes complete dogshit not even ten episodes in. Eventually the plot holes, inconsistencies, nonsensical character motivations, contrived melodrama, overused tropes and cliches, overall very poor writing and the fact that they're still struggling against the same generic mooks since the beginning of the series becomes too distracting to keep watching.
