How bad is it? It's incredibly cheap and looks like it was filmed in a day.
Should you see it? Yes.
I wasn't big on "Jesus Christ: Vampire Hunter" and this Jesus as a superhero film came out soon after, but it surprised me. It's really really cheap, but makes its cheapness work for it, such as in the cheesiest hero costume in decades. Jesus returns, finds that people can't relate, so he has a superhero costume made and thhts the Antichrist (New York City Parks Commissioner - I'm thinking they had some permit problems with him when filming this). The film's jokes run a bit thin in the middle, but the ending is quite good and for once - thank God [perhaps literally!] - the level of humor is above farts, boobs and puns. This might be a cult hit waiting to be discovered.
