Not everybody loved anything about Star Wars: The Last Jedi, but the general feeling on the porgs seems to be that they’re cute, without being too cute.
If anything, considering how many people feel about some aspects of The Last Jedi, the fact is the porgs may have come out of the movie looking better than anything else overall.
There certainly were split opinions as not everybody loved the porgs.
They were fun little additions to the story, without drawing focus away from the things that were important.
