Agree. I don't think I finished the pilot either. I never understood why this show got the cult following that it did. It tried to be scarier/more serious than Supernatural, but with a budget-style that was smaller and cheesier than Doctor Who.
To a scientific mind accepting supernatural is nearly impossible. Constantine wasn't cheesy. It was intriguing and it explored speculative better than many other series. In Hard SF the speculative is often a fantasy element, while in this one, the Dark Urban Horror jumped on your face.
Since you didn't you even finish the pilot, you are dooming whole series based on the bias instead of allowing yourself to explore the narrative more than a half episode. I often don't write episode reviews on the series at their first season, because I don't want to go out and claim it's something that it isn't if I'd bothered to watch some more.
Sometimes it's obvious, but in Constantine case the series was very well made even if the Studio decided to stick their fingers in the production. I suspect extreme religious views influenced the ruling on putting this series down. But they didn't succeed as Constantine is somehow staying on the small screen year after another.
I don't know how Constantine does it, but it seems to me that there are rather large audience out there that wants to see this chain-smoking, trench-coat wearing supernatural detective succeed rather than having it FireFly's destiny.
