Firstly, its against forum rules to accuse people of trolling (not to mention highly pathetic). Secondly I'm not trolling. I'm stating fact.
Its a case of it only being a feature for the select few people that use it. Nothing 'big' has come to OS X in a long time now short of welcomed performance improvements.
Lets actually look at it objectively:
Game center - It has next to no real use if you dont do multiplayer gaming heavily on your mac. Gaming on the mac is already fairly niche (although granted it is growing). Even then, who the hell needs it? Seriously it's such a minuscule usage market. The biggest annoyance is that some tit decided to disable the ability to delete it.
Mail - It's a good app. But its only a good app if you need it. With the likes of very well made webmail clients, it's not something I'd personally ever want to use. Gmail and Outlook webmail clients do a pretty amazing job, and are updated a hell of a lot more often than Mail.app is.
AirDrop - A useful little feature, doesnt work for me however. Never has done, and never really tried to fix it. Certainly not worthy of being listed as a major OS feature.
iCloud - I had high hopes for it. But a measly 5GB free limit, and piss poor performance outside the US made it very much an annoyance more than a feature. Dropbox and Google Drive do a way better job of file syncing. The only plus of iCloud is storing notes in it, and using Photo Stream...assuming you dont hit your limit within the first 15 minutes of using the darn thing! At the end of the day, it's just MobileMe rebranded after the monumental mess they made of it.
Safari - Cant really include that. It's not a core part of the OS. It's a downloadable app.
Drill into the features of mountain lion. Look at Apple's page on it. The feature list really is quite pathetic.
Notification Center - it does an 'ok' job but Growl is still way more convenient than having to keep opening up some silly hidden sidebar that's been bodged into the top corner of the screen. Most apps still use growl however, and will do for the foreseeable future. Especially given that Apple are locking down the OS X features to only work with MAS apps.
Reminders - Should be an optional app in the MAS, not built into the system.
Notes - The same as reminders.
iMessage - Nice. But never works for me on any of my machines. Spends ages spinning a wheel only to tell me it couldnt connect to the Apple servers. Littlesnitch doesnt even show it trying.
Facetime - Same situation as iMessage
(A note about both iMessage and Facetime - dont forget that these replaced iChat. So only half a feature there really)
Power Nap - Not a notable feature
Dictation - Only a feature if you do a lot of writing
Sharing - Only a feature if you want to annoy people on Facebook and Twitter by posting junk all the time.
Facebook/Twitter Integration - I'd rather not have Facebook baked into the OS - there's no need for that - EVER.
Airplay - possibly the best feature of Mountain Lion. This one actually has its uses!
GateKeeper - No. Just No. If you think this is a good idea, you either dont understand anything about tech, or are very naive.
Then they list "Over 200 new features". Most of which are individual tiny things like
reordering table headers using voice over - thats not worthy of being called a feature. I'm not exaggerating here either -
thats actually listed as one of the 200 features:

Am I being negative? You bet your ass I am. However out of everything I've listed as a "Feature" of Mountain Lion. I can honestly say that I've only ever found Airplay to be helpful. Even then I've only used it once in a blue moon.
Its not as if I'm a light user either. I'm on my mac from 8:30AM to about 6:00PM Mon-Fri working.

All of that means nothing.
I'm talking about a core OS feature here. To the end user, all they see is that Apple took the perfectly functional Quicktime they had on their previous OS X release, and 'dumbed it down' by removing a bunch of features. Then to add insult to injury, replaced said features with a pathetic social network integration where you can share videos to facebook/twitter.
