SPOILER FREE DISCUSSION of new STAR WARS ahead, but avoid if you want to go in completely clean.....
I think even if you weren't a fan of Ewoks, you could like the Porgs, or at least if you hated Ewoks, you might not hate Porgs. Ewoks were heavily involved in major plot points and strained credulity a bit taking down million credit war machines with pointy sticks and small rocks. Porgs are just there for comic/cuteness relief. They are one of the fun creatures that normally just sits in the back ground of Star Wars movies but put in the foreground for a few very brief scenes.
Overall, I really liked the movie a lot. It was definitely strange for a Star Wars movie, and both felt like one and didn't. Its hard to explain but it subverted your expectations on what to expect from a Star Wars movie, but it leaned into those expectations to set up the reversals. There was also the usual amount of fan service to old movies, but really well done so as not to be intrusive. Critics (media) loved it but a lot of fanboys (or at least a few vocal ones) hated it. While I am a Star Wars fanboy, I agree with the media. It is a very good movie that's biggest strengths were its emotional payoffs and the way it completely subverted expectations. It definitely ran too long in the middle and there were stretches that were a bit tedious. Some of those sequences seemed to serve no purpose to the larger narrative but fit thematically and for character development. There were some eye-rolling plot contrivances as well (my biggest gripe). But they all lead to what was a really good payoff, so are very forgivable. Despite it being a darker movie in the vein of Empire, I was left with a greater sense of hope than any of the other Star Wars movies before it.
If you are a SW fan, go in with an open mind. Don't expect a repeat of the original Trilogy (although Force Awakens got bashed for doing just that). If you are not a huge fan, I repeat, go in with an open mind. You may enjoy the way it subverts genre tropes and expectations. One of the best new characters is not at all what you would ever come to expect from a space opera hero, and is all the more effecting because of it.
Final note, the fanboys moaning elsewhere on the internet annoy me. Why do people find the need to tear things down? They want more of the things they love, but they want it to be different while being the exact same as well. Good luck. To me it seems like they just want to rips something apart, and the more beloved the better. I swear, if they aired Empire and added three to the Episode number, people would still find a way to rip it apart. Many of the complaints I heard about E8, could be laid at Empire. "Humor at inappropriate times undercut seriousness"....In Empire, the I Love you, I know scene, check, Chewie putting 3P0 head on backwards while Han is being tortured, check.. They complain that some plot points that served no ultimate purpose, while ignoring the thematic and character building aspects. Well all of Empire except the big reveal served little purpose. Luke's hand get s cut off...robot hand. Han is captured...rescued 20 minutes into the next movie. C3Po get blown up...repaired. That's not to say Empire is bad, on the contrary its a masterpiece. The events served for character development and theme. My point is that people complaining about E8 and revering E5 are on very shaky ground based on the reasons I have seen.....<sigh>Ok, rant over. Sorry, I'm reading some comment boards with people hating on it and needed to vent here where its hopefully not going to blow up into a big thing.
