João Beleza Freire’s review published on Letterboxd :
Really great, improves on the original in every way.
Hugh Grant's character was brilliant as the antagonist. Well written, both captivating and funny. Unlike Nicole Kidman's character in Paddington 1, he adds to the story instead of just existing in it as an archetypal, irredeemable villain.
I like how Paddington isn't framed as a can-do-no-wrong saint just getting caught up in bad situations. Some scenes (like the barbershop one) show him messing up and struggling to come up with excuses instead of admitting his fault. It's subtle, but is a nice touch that makes him more sympathetic.
The writing and editing were once again economical and effective. Art direction was even sharper. The pop-up book fantasy scene that takes place early on stands out — it's especially memorable and affecting, doing so much emotional work with so few ingredients.
I can see now why this has received such high praise. It's well deserved.
