I watched this without knowing anything about it and found it to be well made and fun with a good cast and great practical effects.

The only thing I didn't like was the protagonist, which is a shame. I understand he's supposed to be awkward but right from the bat he's extremely annoying and very unlikeable, his acting is too much over the top, and the character doesn't improve or develop in any way through the story.

The rest of the cast is not so bad, but feel like they're just in there as a filler.

What really made me watch and enjoy the whole film was Jeffrey Combs and Olivia Taylor Dudley. They are the high points and it's worth watching for the two of them.

This film had a lot more potential, It could have been rated higher if the main protagonist was more likeable (not such a loser), or he developed and grew in some positive way through the story. Or if the actor played it normal/straight, and not like a caricature.

The humor is good for a chuckle, but it's sometimes too childish. If it had been straight or dry humor like in the original Ghostbusters, it would have been amazing.

Onyx the Fortuitous (Andrew Bowser) is a loser and a follower of Satanist Bartok the Great. He is excited to be one of five fans selected by Bartok to join him in a ritual to raise a demon.

I don't know anything about Andrew Bowser. Apparently, he is famous for this character. It is a character for specific taste. At first, I like his loserdom. I accept his voice as a part of that character, but that does wear thin after awhile. There is a whine to it that can be annoying. Then something happens to me. I actually started to appreciate his commitment to the bit and felt sorry for the character. I can see both sides of the criticism.
