Generally, The Haunting Hour is a significant improvement on the Goosebumps series from the 90s. Better production values and acting all round. This episode, however, is absolutely atrocious. The youngest child simply cannot act, the 'creature' is an appallingly unconvincing puppet and the pay-off ridiculous. Basically, a warring family (including soon-to-be-divorced parents) are magically united in love after about 30 minutes trapped at the mercy of a rubbish puppet . . . er, sorry, 'terrifying gremlin'.
There is nothing commendable about this episode that warrants anything higher than 1 star. Truly dreadful.
