Connecting emotionally might be a stretch but there's definitely enough human traits of a Predator to cheer for them or be invested in what they do. Scar and Fugitive showed they know how to communicate through hand gestures, they've got a sense of honour to a degree and they're even capable of being a bit snide e.g 'Shit Happens'
Get the right story and execute it correctly, you'll be cheering for the Predator no problem. It's not that hard to cheer against humans anyway, we'll f**k each other over for a percentage.
