Don't forget to read a variety of reviews. The 6-star reviews seem the most accurate.

Rating: 6/10 (4 May 2019)

That is not a self-serving review title. I rated the movie a 6 after reading a variety of reviews here on IMDb. The 1-star reviews are more poorly written than I've ever seen before, though I think that's because the Avengers have such a global fan base that more non-native English speakers are weighing in with their (well understood) disappointment, which is cool.
I didn't have to read too many of the 9- or 10-star reviews beforehand because I was already committed to seeing this movie after Infinity War, and anyway I read some article on a news website about all the gushing, raving tweets from early Endgame viewers so I was actually fooled by the hype from a non-IMDb source for once. But, in retrospect, the 9's and 10's here appear to be mostly from the corporate shills and fan bois exactly as one would expect.
So, I went to the middle of the pack of reviews and found a lot of really well thought out reviews in the 6- and 5-star range. Since there are already so many good reviews, I'll just pile on, buck-buck style, with some random musings...

Was anyone else wondering why Ant-Man didn't call his daughter "Peanut" when he saw her again? To him it was only a little over 5 hours plus a day or two, but he still understood the vast amount of time elapsed in the main timeline. Either way, you'd think he'd still be using his pet name for her.

OK, I have new respect for that scene in Iron Man 2 where Tony invented a new element (I think it was called "triangulum"). You remember, when he used that giant monkey wrench to get his laser ring aligned? I always thought that was silly, but it took him an eternity compared to how quickly he solved the time travel conundrum in Endgame.

Oh yeah, sorry for burying the lead... Infinity War was way better and I am quite certain that many film and MCU fans will just consider it to be the end of the series. I think I might be doing that right now as I type.

Hahahahahaha. Sorry, I am just laughing thinking about how pointless Captain Marvel's movie was. They shoehorned it in at the end of the series, right before Endgame, and it was completely unnecessary and added nothing to the narrative.

Solo movie or not, Captain Marvel's brief ex machina appearances at the beginning and end of Endgame could not have made any less sense or been any more of a cop-out. On the other hand, I fell for the Captain Marvel hype machine also, so I guess Disney has the last laugh (and my ticket money).

OK, I admit, I really liked Captain America's hammer-wielding moment - it's definitely my favorite part of the movie. That was his version of Wonder Woman's "No-Man's Land" scene. I guess it didn't hit me until reading all the reviews afterward that this cool moment came at the expense of Thor's reputation (i.e. that's why he had to be fat and mostly useless for the entire movie, just to set up that scene). I can see why Thor fans are enraged.

Ummmmm.... really? Send the two most human and normal Avengers out to get the most outer-spacey and scary Infinity stone? Yeah, right.

Since Hulk usually ruins most of the movies he's in, I'm actually glad he was a Banner hybrid for the entire movie. Really, Thanos should have dusted him and left Peter Parker, but I guess we needed somebody really lovable to be dusted in order to make us care about Endgame.

Dang, the Hollywood pecking order is tough! Bradley Cooper rates higher than that Peter Quill guy, even in cartoon raccoon form. I know, Taylor, I can't do that - mix actors with characters - but I can't remember Star Lord's name. Oh yeah, Chris Pratt. I only remember from tabloid articles about his love life. To be fair, I guess Rocket really is the most entertaining of the GotG so it makes sense he gets the rabbit's share of Endgame screen time.

Hahahahaha. Sorry, I'm just laughing again remembering how the Winter Soldier always brings his high-capacity assault rifle to all the epic battles between gods, hulks, titans, space aliens, laser plasma metal jet suits, meta-humans, etc. It seems pretty effective though. He should be the official Avenger of the NRA.

Was it me, or was it way too easy for Thor and Rocket to get their Infinity stone? If you're going to send the Avengers off on 3 side quests, at least try to keep them balanced! Then again, Infinity War made me want to go back and watch Ragnarok and Dr. Strange; Ragnarok and Endgame now made me need to go back and watch The Dark World, and so on, and so on...

Endgame proves that there is absolutely nothing - nothing - that Hawkeye can do to make him seem like a legit Avenger. I'm sorry, he just doesn't fit in with the rest of the heroes. I don't know what it is, he just doesn't.

If you're going to mock other time-travel movies' "rules", you better come correct with your own. Endgame definitely does not do this. I haven't seen one movie so unfairly diss other movies since Harold & Kumar went to Guantanamo and dissed Eurotrip.

I'm sorry. Iron Man has survived a lot of blasts before. I think he could have survived the Infinity Gauntlet snap.

I get that it's a big Marvel movie thing for the heroes to run around without their helmets/masks on way too often so you feel a big personal connection with them rather than thinking you're watching a cartoon (spoiler alert - these movies all seem like cartoons anyway), but this went over the top in Endgame.

Captain Marvel out in space and ripping through Thanos' ship without her helmet? Iron Man and War Machine running around without headgear? Come on, it's just stupid and reckless - and it cost Tony Stark his life!

Since Chris Evans upgraded from Johnny Storm to Captain America, I think it's completely fair that Anthony Mackie gets an upgrade from Falcon to New Cap. He has a nicely trimmed beard. But he damn sure better take some of that super-soldier serum to keep it real.

I can't remember what other movie made me cry this much. I think there was one. Interstellar? Maybe. Infinity War? No, I don't think so, I think it had only two tear-jerking scenes, Endgame had three or four, I lost track.

Endgame is a huge letdown compared to Infinity War. It's at least 30-45 minutes too long, has an uneven pace, way too little comic book action, and it contains lots of stuff to make certain characters' fans really mad.

Even so, I think the best reviews are still in the 5- to 6-star range because even the disappointed fans realize what an impossible task it was to try to wrap up the story after Infinity War. The producers and directors at least gave it a shot, even if they missed the mark. Maybe not even Hawkeye himself could have hit that target.
