It certainly is good, but imo it misses the final "Omph" to be great. Nothing much to criticise, a rather constant good level (gets a bit weaker in the 2nd half imo) but also no memorable highlight in my eyes.
Certainly not a must see, but if you plan to go to the cinema anyway, BP as a very solid choice.
I've seen it and I'd strongly disagree with this assessment, for me it's definitely a must see and in my top 3 Marvel movies. I'll try to address how I see some of the criticisms you have with the movie and offer an alternative opinion below.
I'm a little confused about the "Omph" moment comment for me it was the choice Killmonger makes at the end... a very Magneto-esque thing (which I'll talk more about later) to do IMO and for may blacks in America who face similar quandaries about identity/selling out/the past/etc. it hits very close to home.
Funnily enough most critics say it's the beginning of the movie that is weak claiming it feels more like a spy movie vs. a superhero movie... of course I'm starting to think perhaps the expectation for superhero movies may be off since Black Widow and Hawkeye are both considered superheroes (with no super powers and only agent/spy training).
I think what makes the movie memorable was how easy it is to empathize with the villain Killmonger's motivation (a serious weak point in nearly all Marvel movies up to this point)... honestly the ideologies of both Killmonger and T'challa gave off a very Magneto vs. Xavier (or as Stan Lee has often cited a Martin Luther King vs. Malcolm X vibe since that is who the characters were at least in part based on) vibe for me that I found refreshingly thought provoking (something I really haven't experienced with a Marvel movie up to this point), especially as a black person in the U.S.
I even have a hard time calling it a superhero movie. Yes, the characters jump higher and the swords are glowing, but thats it. The same story can (and has several times) be told with just regular persons. There is nothing really "superheroish" happening.
I'm having a hard time parsing this... What is "superheroish" in your opinion? Are movies like Captain America and Wonder Woman (basically just war stories with a superhero included) not "superheroish"? I'd definitely need to understand the definiton you are using before addressing it but I'll say most superhero stories could be told with regular people if interpreted at an abstract enough level...
There is also hardly any reference to other Marvel movies in BP. They acknowledge that Civil War happened (kinda had to as BPs father died there), one indirect reference to civil war and one after credit scene. Thats it.
If I'm recalling correctly few if any of the movies introducing single heroes to the MCU (Iron Man, Thor, Captain America, Dr. Strange, etc.) reference other Marvel movies with more than a nod... so not sure why BP in his origin movie would necessarily buck that trend, especially since Wakanda is an isolated nation. We've already seen his connection to the Avengers in Civil War so anything beyond a mention of that would, IMO take away from his origin story.
