X-Men I thought was easily the best out of all of them IMO. Just the right amount of action and a pretty strong story as far as comic movies go. I'd give it a high recommendation, and after a first viewing I'd say I even liked it as much or more than Edge of Tomorrow.
So far Yosemite looks pretty good. Standard upgrade stuff with new icons and some upgrades to the standard mac programs like imovie, pages, etc. I haven't explored all of it yet, but it was a free upgrade so how bad could it be ?
EDIT: I take that back. I don't yet know how to fix it or if there is a fix, but the old green button no longer resizes the window to match the size of the content within. Now when you click it it takes you full screen where the top menu bar disappears and reappears and you can't minimize anything. I hate it.
