There are many long standing Halo players and they all have different views of the franchise.  There are many that loved ODST but hated halo 3 or loved Halo 1 but disspised Halo 2.  Just because someone is a fan of the series does not make their opinion any more valid then the next guy.  Actually I find that these fans who get so wrapped up in what they believe a certain franchise is are the worst when it comes to reviews.  Their opinions usually are so bias and screwed to whatever they feel the game should be instead of playing the game for what it is. 

After finishing the game, the things Joe brings up are valid knocks against the game but does that mean his score is representive of the SP or even the complete work.  If you value Joe's opinion then yes but just like any opinion, not everyone will put as much weight to the knocks as some.  The only knock I have against Halo 5 is no split screen but I totally enjoyed the story probably because I finished Halo 4.  I played on Heroic so the campaign was 8 hours + for me and just enough so that I did not become bored.  The AI was just as good as the other series but will say your Team AI can definitely do with more work.

He knows that by being over the top, he will get noticed. People love to see other people rant and get angry, hence the name Angry Joe. I don't believe he gets bribed but I do believe that he often plays on the negatives simply because it gets hits and gets people talking(as evidenced in this very thread). You don't see 220 replies to an IGN/Gamespot review even when it is low.

Works for the Angry Video Game Nerd.

Hey, just cause you like bad content, doesnt mean i do. I will just report when i see forum rules beeing broken. It obviously hopeless to talk sense into people in the internet.

Yes, you may cry all you want. I'm too old for that. Also i'm immune to internet insults so i laugh at your pathetic atempts.

I think people were pissed about a lot more things than a cliffhanger-y ending

Really? There was nothing cliffhanger-y about the ME2 story. It all wrapped up quite neatly. The only people who might be pissed are those who thought the whole story would be done with in the second game. But it proabbly would have taken just a few hours of playing it for enyone to realise ME2 wasn't going to be the final chapter. I think impatient anticipation is what fans of ME2 were feeling, not pissed offness. Well at least I was full of anticipation. Though I also had the advantage of playing the late PS3 port, which meant less time to wait.

You missed the point of what I'm saying. It seems to me that a lot of the people bitterly complaining about Joe's review think he's being motivated by an inherent negativity towards Halo. But what Joe claims is that he is motivated by an inherent love for Halo. It doesn't mean what he says and thinks is wrong or right, but motive for why you do or say something is important for people to judge for themselves whether a point of view is unfair or negatively biased. My interpretation of Joe's review, being that I have no emotional investment in Halo at all I feel like I am in a position to be reasonably objective, is that his motivation behind his review is not questionable. So what I'm saying is that I think people are being unfair to Joe. I don't really care if they agree or disagree with Joe's specific criticisms or his score. 

The ratio of likes is also very high for the video.

I believe that's because although being OTT, he is one of the few reviewers that isn't afraid to tell things exactly as they are... i.e: micro-transactions are ****, no matter how they appear to be dressed up.

Say what you will but people still kept going to see those new Star Wars movies. And definitely couldn't wait for the 3rd ep to come out.

No it didn't wrap up neatly. It did exactly what the majority of 2nd entries of a trilogy do by showing a huge threat/dilema is on its way for the next one. 

Yes, well there's no accounting for taste.

The game was neatly wrapped up. What you're talking about is the post-script, which is not the same as a cliff hanger. The post script is a teaser.
