Opinions of it are so diverse I would say go ahead and see it. You might enjoy it like Scooby did.
What is so disappointing is this summer has been a bust. Yes, Finding Dory as been a hit but it wasn't at the top of my list of movies I wanted to see. ID:R was just dreadful. I was expecting it to be "bad" but enjoyable. It was worse than bad, it was boring. It wasn't enjoyable in the least. BFG was Spielberg, Disney and a popular children's book. Magic waiting to happen! Not even close. My expectations for this were as low as they have been for any film but the positive reviews gave me a glimmer of hope. It wasn't a steaming pile of crap, but it didn't live up to even mediocre expectations. If Star Trek, Lights Out and Suicide Squad don't deliver this could be a terrible summer for movies.
