This movie entertained by 12 yr olds from start to finish. The action starts immediately and, other than a one to two slow spots, keeps kids entertained throughout. Karloff's monster is perfect - a true classic movie creation. His walk, is blank facial expressions, oversized suit, and drooping eyes are perfect. The scene with the little girl might be a little disturbing for some kids. As this movie came out 4 years after sounds was brought to film, the audio can be a little grainy at times. But, this movie is well worth a watch. 'Bride of Frankenstein' is considered an equal to this movie. And, if you are ever going to see 'Young Frankenstein' with the kids, then this is an essential prerequisite.
