I like River, but she's never been my favorite and I can understand people being tired of the character. I actually liked her a lot more in Silence/Forest than in the Angels two parter - that soured me towards her, but I really enjoyed her again in Pandorica/Big Bang. I wish they'd spent more time on the revelations of her background in Series 6 - for what should have been pretty meaty stuff they just breezed through it.
I'd be perfectly happy if she's had her send-off, though a Jack and River show could be a lot of fun too (though I'd really like to see Jack back at all). But not before a Vastra and co. spinoff.
