I will not hold the producers of this series accountable for the drastic changes made to the character of The Night Man. In the comic books all he has is the one power, and though it is a really cool power, it is not extremely valuable on its own. The plot line of a first season episode actually revolves around this somewhat humbling fact. Because of this, The Night Man is not what you might call "made for TV", so I think some changes had to be made so that his character would look good in a Fantasy/SciFi/action genre. On a syndicated budget, this is a very tall order, yielding the cheesy results that have been mentioned in other posts. As far as the acting, it may not have been award-winning, but neither was it career-killing, and the music was excellent, thanks to Marc Bonilla. The writers did do a poor job with continuity, and some of the dialog seems a bit forced, but that just makes it even cheesier and thus much more enjoyable if you are in the mood for it. Syndicated TV series have, for a long time, been providing cheap thrills and guilty pleasures. At this, The Night Man series excels, making it a show well worth watching.
