Apple Ios8 disappointing

I've seen the hyped ios8 but can't help feeling disappointed. Why would Apple make a 64-bit system then create blocky 8-bit graphics?
Apples mantra was once "it should just work" but really, it doesn't. My iPad and iPhones have gotten slower and buggier:
my message screen keep creating new contacts.
iMessages are delayed.
Messages no longer synch between my iPad and iPhone, creating fragments of confusing conversation.
Safari keeps crashing when I log in to website to buy stuff. 3 attempts before it holds was the last count.
Voicemail list has gone.
My iphone 5s has lost wifi reception. I need to be on top of the hotspot to connect.
I don't want a health button. That's not cool. Somebody who needs to use an app to be told you are unhealthy should probably get out more, lay of the internet & get a life.
I don't buy from iTunes so why am I forced to have it.
Why doesn't spell check recognise the word mum and capitalise it as it does for Dad.
Both my ios 7 machines often run dog slow. Press a key wait 10 seconds. I just want to back to ios6. Anyone else want that?
