My experience of this anime can be summed up by the word "meh". I went into it hoping for a nice twist on the seven deadly sins being the good guys, and some awesome fight scenes, and ended up sorely disappointed. Sure, the characters are known by their sins, but rather than be actual embodiments of said sins, they were simply granted them as derogatory titles, so they fail to stand out as shounen manga characters in that department.
The characters don't undergo any sort of development across the series, and for the most part are bland and boring. Ban is pretty fun because of his aloof yet silly attitude, and the rest have some decent humor, but this is definitely not a high point of the series.
The combat was especially mediocre. The fights only ever focus on Meliodas and Ban 99% of the time, with the rest of the sins just acting as accessories. This is especially frustrating after so many of them are hyped up as 'the strongest of the deadly sins', or 'the prince of fairies'. I particularly was looking forward to Diane kicking ass, but we only ever really get one awesome moment out of her when she punches through a supposedly unbreakable barrier. The rest of the time she's either sleeping, 40 miles away, or has a hole punched through her chest and has to act as a damsel in distress. Ugh.
We do get a couple of good battles in, but the majority only last a couple of seconds, due to the characters' (see: Meliodas and Ban's) overpoweredness. Only two or three fights really give any true sense of danger, and one of them was ruined for me by how easily Diane went down. But that's just me.
I kept watching because I expected a more even playing field eventually, with all of the sins being equally capable, but that unfortunately never happens. Meliodas and Ban are, throughout the anime, just complete male power fantasies, while the rest of the crew just gets swept under the rug.
I don't hate this anime, but I don't recommend it. It's not bad, just decent, and really not worth your time. It lacks any aspect that really stands out, and ultimately just falls flat, lost amidst a sea of better, more entertaining shounen anime.
