Just a short review cus I don't like Vanguard anymore. Heck, the whole show is a so bad that this small review is enough to roast this bad anime.
Story 1/10
The story is of little to no consequence. Some kid gets bullied, gets his favorite card stolen and then uses card fighting to get it back. Suddenly the people who bullied him become his best friends and he's no longer the loser of his class. They especially note this in the second episode where they point out that before he had his card fight, he was a ridiculous loser with no friends and never talking to anyone, never being happy. Yup, worst story I've been in a long time
Animation 2/10
It's your Generic card fight animation. Flashy lights when cards are used, random spirits popping up left right and center, colorful hair for no reason other than to... actually, I don't know why. I was going to say make it seem original, except every single anime does this. So colorful hair the sake of it? In short, the animation is about as Generic as it gets
Sound 2/10
There's not much to say. You don't really notice the sound. It doesn't help nor hinder the anime. It's practically non-existant, which probably makes it the best component of this anime
Characters 1/10
If I could, I'd give it a -10. You have your main character who's a whimpy little brat, then you have your side characters who consists of two bullies who magically become friends, a quiet mysterious shop keeper and a brooding quiet other person. Because creativity and interesting character design with depth is over-rated
Overall 2/10
This is amazingly generic. Someone must have slept their way to getting this into anime form because there's not a single interesting thing about it. The characters suck. The story is non-existant, the animation is bland and generic and the entire concept is proposterous. I only watched it for four episodes because I was hoping something interesting would happen, and the first three episodes were just scene setters. I guess not.
