I loved the Goosebumps books (and less so, but still, the TV show) when I was growing up. I think if a kid watches this weird interpretation now, at the age that I was then, they might enjoy it. But for me? It didn't work. I actually did appreciate more than I thought I would, but based on the trailers my expectations were abysmally low, so that's not exactly saying much.
Final rating:★★ - Had some things that appeal to me, but a poor finished product.
