Granted, I enjoyed Taken and Unknown, but along with the likes of Taken 2, Non-Stop and A Walk Among the Tombstones, it seems that he's playing the same fella over and over again, in movies that largely follow the same type of formula. Hell, his wardrobe doesnt even change that much in these films. I bet you that if he came round to your house for a drink, he'd be wearing the same type of gear.
I love Neeson, but I'd like to see him do something a bit different than these fomulaic films, seemingly just for a big paycheck. Maybe a comedy - the big man was absolutely hilarious in Life's Too Short.
