Berserk of Gluttony tries incredibly hard to be cool. This is supposed to be your edgy power fantasy that lets you see your worst enemies suffer hell ten times over. And what do you get? Hell, ten times over.
Fate, the main character, is able to communicate with his sword by exchanging thoughts with it. The author thought it would be a silly little joke to write a scene where Fate accidentally replies by speaking out loud instead of using telepathy. Wouldn't that be funny and embarrassing with other people around wondering why he is talking to a sword? No. This joke however is part of the Berserk of Gluttony routine. You get this joke regularly and it baffles me. Repeating the exact same gag, with no twists or changes, again and again is nothing short of insanity.
The main issue however is that the series tries to sell itself as an action packed epic adventure, yet you don't get to see any of it. Some of the monsters that Fate has to battle don't receive more than. One. Singular. Frame. Afterward, they disappear in a large cloud of smoke or some mediocre animated explosion. At this point, you could just show the manga panels and play music. This show calls itself an Anime, but you are a fool if you think it contains animation. I have seen my fair share of low quality Anime, but this one takes the cake and then some. Nothing but pain. The episodes felt like dentist appointments. I never want to hear from this show again.
