No, they wouldnt. Nor did Jar Jar ruin TPM and Ewoks RotJ. One is a movie with so many other problems that when people complain about Jar Jar 'ruining' anything I wonder if there's something wrong with them. Ewoks were also poorly handled, but by George's own admission they were there to sell toys. Porgs, no idea. But they can't ruin the movie. If there's an issue with them, its a symptom of a much larger issue

Mehhhhh they probably learned from Jar Jar so they won't make them talk (too much) or be important to the plot.

Will small creatures with no dialog that are probably featured prominently for less then 1% of the movies run-time ruin it? nah.

Lol I was thinking the exact same thing. They’ve shown a new alien race and now people are getting upset and jumping to conclusions. But as you said it will hardly be in the movie to ruin anything.

I think it'll depend on how much screen time it gets. If it's just something that exists mostly in the background without making annoying noises mostly sticks to the back of the picture it'll be fine.

HOW DARE THEY!

If I wanted to see women in action, it better be in the kitchen or the baby making room! The only weapon suitable for a woman is a rolling pin!

In the original movie, the death star gave R2D2 a blowjob, have they not shoved those dag-nabbit robosexuals down our throats enough?!??!?!

At least they made up for all the black-washing in the 2nd and 3rd movies by making all the Nubians white in Episode 1.

Damn snowflake, starfish, cuck, libtard SJWs!

Enron Paul 2012!!!

Yeah I'm kinda curious what they're supposed to do off that island. Also how much screen time is left for not only BB-8 and that evil BB-8 but also where is C-3PO and R2-D2. 

They're so cute though, I want one.

Bow before your new master Star Wars fans! :D

They have been seen in only one instance in the trailer, and for some reason, that's all anyone can seem to talk about. So, yes, they will ruin it.
