Zero no Tsukaima (The Familiar of Zero)
It's hard to know where to begin with Zero no Tsukaima: whether to start by gutting the laughable excuse for a plot, perhaps castigating the clockwork collection of characters, or perhaps even starting on the atrociously simplistic animation and aesthetics. From all of this one could be certain that it is a show without merit, and while critically that is true, there are several aspects which I'm sure could make this a guilty pleasure for a select few.
Based off a series of light novels by the same author as "Green Green", Noboru Yamaguchi, and produced by JC Staff, the series has penalties before it even begins. The first episode does nothing to allay these worries and produces cliché after cliché in both characters and plot. The protagonist is a failing mage called Louise who summons an affable idiot from modern day Japan into Tristein Magic Academy; already it is fighting against other "fish out of water" anime and the obvious inspiration from Harry Potter. The rest of the series carries on regardless and stumbles through hackneyed and quickly ignored plot points and culminates in a poorly orchestrated and wholly expected "battle" intermingled with predictable character hook-ups.
