I wanted to watch this last night, but I couldn't find a stream, so I watched it a few minutes ago. First of all, most of us were probably thinking, "wtf is The Goldbergs, and why did Robert Englund agree to this?" The answer:
This show is set in the late 80s, so they want to throw around a lot of cultural references at the time. This "Halloween" themed episode was about horror movies and over-parenting your children. Some dork is trying to watch Nightmare on Elm Street, and then what do you know? It gives him nightmares.
Everyone excited about this episode wants to know about Freddy's presence. There's a "nightmare" in which she encounters Freddy (who she calls Fredward Kroger) and the two squabble in a minor chase, talk about parenting, and then get their f-words bleeped. Then, Freddy gives up and she wakes up. That's really about it. He came out of retirement for this shit? Being a sitcom, the whole thing was super cheesy, so it mostly comes off as embarrassing. I hope he got paid a lot of money for this shit.
