MN hatred isn't really true. If you start from there you'll probably fail!
I had one MIL I loved and one I couldn't stand. What were the differences? MIL 1 (bad) MIL 2 (good):
MIL 1; DH could do no wrong, golden child, sun shone from his arse. MIL 2; DH was a human being, with flaws and pluses and she recognised both while loving the bones of him.
MIL 1 wanted me to be her 'daughter' and do lots of things she liked with her. Call her mum and the like. MIL 2 got to know me and we found common ground. Knew I was a DIL, not a daughter.
MIL 1 interfered. MIL 2 told me I was great and not to let DH get away with any nonsense 
MIL 1 couldn't understand that because I was better qualified than DH, better educated, harder working, motivated, and more intelligent, that I might want a job and money, not to immediately produce grand babies. MIL 2 loved hearing about my job and never mentioned kids, until I got pregnant and she was over the moon.
MIL 1 bought me a jumper I'd never wear for Christmas, 4 sizes too bog. MIL 2 came to the hospital after DD was born with no present for DD and a crate of my favourite soft drinks. It was worth 200 times as much as any flowers or presents.
MIL 2 was a diamond and I miss her a great deal.
