I must have watched a different Marley & Me... I found it predictable and it didn't move me one bit. And I'm usually an ugly sobber!
Not a film, but to give you an idea of my sobbing credentials, not only makes me cry every time I watch it, but I cry when describing it to people 
Precious was a hard watch for me, I cried a lot. Actually had to pause Still Alice as I couldn't hear over my own hysterics. Similarly to Glistens, I wasn't just crying about the film, but also about a family situation. Although not Alzheimer's, it was just too near the bone. DP would rather I didn't watch it again, as he had to cope with the fallout.
Angelina Jolie's scream/howl in Maleficent didn't make me cry, but I found it an incredibly powerful moment. Don't want to ruin it for anyone who hasn't seen it (and definitely watch it, it's great), but it's such a raw scene, with a huge emotional impact. Just wow.
Oh, and Mamma Mia, the wedding dress and Slipping Through My Fingers had me howling. I watched it with a couple of bottles of wine and found it so cathartic that I was on my second viewing - and howling for the second time - when DP came home
the shame!
