MINOR SPOILERS!!
This movie was amazing. I have no idea why people hate this movie i really enjoyed it.
First of all the comedy was top tier and did not fail to impress just like the other 3 movies.
Secondly just because Po had his own adventure without the furious five doesn't make it bad.( it would have still been cool to have seen them more though).
Lastly i loved the dynamic between both of Po's dads and how they had their own side quest and bonded it was really nice to see.
Overall this movie was a blast to watch and i don't think the movie deserved the low reviews and hate it got.
