Better than Bleach, but that's not saying much at all.
Gurren Lagan - Dumb fun and not much else. A lot of it's iconic scenes are also only tributes to far better series such as Ashita no Joe.
Kill la Kill - Same, though Re: Cutie Honey did it better.
Fate/Zero - Has good animation but that's it. The first season is just "death battles" where nobody of importance dies whilst the second season takes away the engaging aspect of debating who is the side we should root for with it desperately trying to say "Hey guyz. Kiritsugu's da main character!" and the ending is as pretentious as you can expect of most Urobuchi works. Still better than both versions of Fate/stay-night, but that's not saying much when that's just a generic Battle Shonen/Harem series based on a Hentai game.
Death Parade - Absolutely nonsensical, given the afterlife is flawed in that even if a soul manages to avoid going to the void and reincarnates, they have to do the whole thing again after their next life ends, making it an unfair cycle. Beyond that, there's barely any plot anyway and the Opening's the only decent thing about it.
Don't recommend any of them.
