As someone who grew up reading the books and giving every atrocious cinematic attempt the benefit of the doubt, I am pretty pleased with this one.
I winced when I hit play, and settled back, prepared to be disappointed.
I finished every episode in two days, and am excited for the next.
It is very much a show aimed at teenagers, so it has the high school shenanigans and drama. The acting skill varies, as does the script writing. Justin Long is Justin Long (which I love. YMMV).
Every attempt at trying to exactly duplicate the stories and spirit of the books has failed miserably, so this show went in a different direction. They used a Goosebumps villain and created a framework from it, then wove different Goosebumps stories into an episodic/serialized show.
If you're looking for Masterpiece Theater, this ain't it. If you're looking for something fun inspired by delightful Goosebumps books, enjoy!
