If I were rating Gal & Dino purely off enjoyment, it would probably get a 7. Maybe I'd bump it up to an 8 if I were feeling generous.
Here's the thing - I cannot consider this an anime. It is a sketch comedy show split between animated segments, claymation, and live action.
If you are frequently drunk and/or high (as I usually am), then you will probably highly enjoy this show. I sure do. G&D is off-the-wall, weird AF, and random as hell. If you like that type of thing, go for it.
If you are expecting a sincere, well-written anime, do not bother. You are wasting your time. This show is for viewers who do not give a damn about quality storylines and are just looking for something random and silly.
If you like late-night programs on Adult Swim and you have a bong or some dog food in font of you, and you want some total goofiness, then please, watch this show. You will totally love it.
I NEVER rate anime this low. A score of 3 is pretty much always the lowest that I'll give. Anything lower, and I would just drop it entirely and not bother to rate. But I am giving G&D a 1 out of strictly principle.
This is not an anime. This is a sketch comedy with some animated segments. Therefore, it gets the lowest score. I joined MAL to rate anime, not sketch comedy shows. If you want to get on the "well it's Japanese animation so therefore it's anime" argument, then do what you must. But as someone who has watched hundred of anime series, I will stand by my opinion that G&D is not an anime.
If you are weird like me and enjoy off-the-wall humor (and you usually party while watching your shows), then by all means, go for it.
If you are looking for a sincerely good and well-written anime show, then you've come to the wrong place.
G&D gets a 1, as it is not an anime IMO. I'm here to rate anime, not Japanese sketch comedy shows. And I felt I had to justify my 1 score with a review. This is a very fun and entertaining series if you're looking for something weird, different, and amusing. But it's not an anime, at least IMO.
