I enjoyed it very much.It's very funny and I understand some people are disappointed it hasn't to do almost nothing with the 1 and 2 it's still great. Very great cinematography and it's at some degrees relatable.
If you don't compare it to the 1 and 2 it's a 8 or 9 easily.
I recommend it especially if you are open for a little bit of more offensive humour. And it shows how the music taste has changed over the years and it (in my opinion) captures greatly the differences of the generations and mindset.
