To start off, No. This isn't a "FNAF" movie rip off. Anybody who reviews this film and claims it to be a FNAF Ripoff is most likely a child who doesn't know how to properly examine the movie for what its worth.
So, is this movie worth watching? Kind of.
Willy's Wonderland itself is a film about demonic animatronics that need to eat humans due Satanic ritual reasons. One of the only things that make sense is the reason for why the towns folk lure people to the restaurant to have sacrifices. After that it does fall short.
Many characters act out of line very fast and make dumb decisions since the moment they get inside the restaurant. All their deaths were cheesy and could've 100% be avoided if anybody had common sense. Nicholas Cages performance is okay and although he doesn't have any lines, it doesn't make the movie horrible.
Overall, the movie was a solid 6/10, better than the banana splits movie to say the least. This movie had more potential but wasn't able to reach it due to the poor writing.
