i was totally hyped for the constantine tv series, and i enjoyed the first few episodes or so, but after that i wasn't really into it. it's definitely way better than what the 2005 movie was, but it felt restricted. for what the hellblazer comic series offered, i don't think nbc was the right place for a tv series based off its main character.
i thought the lucifer tv series was decent for the most part, but it was like a completely different story than the comics. for a lot of the episodes, i just wasn't involved in them 'til the end, which was usually a cliffhanger for the next episode. i'll probably end up watching the second season, but going into it
neither are terrible by any means. they're just lackluster to me because i expected more from them considering the source material. with preacher on amc, i don't think it'll be too restricted, and the plot is already straying from the comics, but the first episode was fun
