Those who loved This Is Spinal Tap generally divide into two categories: those who love heavy metal and those who hate it. If you fall into the latter, The Return of Spinal Tap is probably not for you. If, on the other hand, you watched the movie and then went out and bought the soundtrack... it's definitely worth your time. You should know, though, what to expect beforehand.
The Return of Spinal Tap is not a satire or a mockumentary like This Is Spinal Tap. It's nothing more and nothing less than Spinal Tap Live. Don't get me wrong: Christopher Guest, Michael McKean and Harry Shearer are still funny as hell; but the brilliant commentaries carry less weight in favor of the music. And why not? The joke could never have been as funny the second time around, so instead, the three just decided to have some fun, returning to their beloved characters and living out the dream of doing a big rock concert in front of a huge crowd. Frankly, the concert segments are much funnier this time around, with the on-stage antics of the three brilliant comedians, as well as winks back to the first movie in segments like 'Rock N' Roll Creation' and 'Stonehenge'. Plus, you get to sing along to all the beloved, cheesy, brilliantly idiotic songs from the first movie, like 'Big Bottom', 'Sex Farm', 'Tonight I'm Gonna Rock You Tonight', '(Listen To The) Flower People', 'Hell Hole' and 'All The Way Home'. Also you get a bunch of great new songs like 'Bitch School', 'Break Like The Wind', 'Clam Caravan' and 'Cash On Delivery' with a rare lead vocal performance by Derek Smalls (Harry Shearer - by now, keep in mind, a Simpsons veteran).
Before you watch The Return Of Spinal Tap, you should ask yourself two questions. The first is - do I really love Spinal Tap, or did I like it just for the satire? If you really loved the first movie, you'll love seeing the beloved old characters of Smalls, St. Hubbins and Tuffnel return. The second is - would I enjoy watching a Kiss concert? If you answered both these questions with a positive reply, watch it.
