That would be Gandalf.
I don’t get Gandalf in the Hobbit movies. Gandalf seems such a meddler in this trilogy. I mean what is he thinking? There’s a dragon sleeping in Erebor that needs to be taken care of ere it joins the growing forces of darkness. Let’s send thirteen dwarves and select a poor hobbit who’s happily minding his own business and send them in to face it. Sure Thorin is rightful King under the Mountain, so maybe we can kill two birds with one stone and reclaim the arkenstone and reunite the dwarf kingdoms at the same time we dispose of the dragon -- but dude... what if they fail and all you do is feed him and his company to a psychotic dragon who would then be awake and ready to terrorize more than just Lake-town? And Gandalf also knows full well what happened to Thror, and he knows Thorin’s going to be in trouble with dragon sickness, but he just sort of keeps ignoring that, even when people like Elrond keep reminding him of it.
Really, Gandalf is like his own self-fulfilling prophecy. "I suspect we're going to have trouble with the dragon, let's go do something about it, oh, look, we not only have trouble with the dragon, but now we've got orc armies and Sauron to deal with." He propels events into action, forces the orcs to attack Thorin's company, forces Sauron to appear. He fails to meet the dwarves so they end up facing the dragon alone and Lake-town gets toasted. He’s quite meddlesome and bossy in this trilogy, and it seems everyone survives the last movie's events despite him, not because of him.
I do not have these issues with Gandalf in LotR. He is neither bossy nor meddlesome there. He’s very protective of everyone and Middle-Earth itself (though he still fails to show up when needed... bad habit of his). But in Hobbit?? Gandalf is very fishy in the Hobbit.
Where in LotR, he answers everyone's questions honestly even when they won't like the answer: "I would not take the road to Moria unless I had no other choice." And he lets others make decisions: "Let the ringbearer decide" -- which includes a healthy measure of Frodo trust right there. In Hobbit, on the other hand, he is secretive, he flat-out ignores Thorin's questions if he knows Thorin won't like the answer, and Bilbo isn't given nearly the trust that Frodo is. It's quite a different Gandalf! I like to think he simply learned his lessons from his time with Thorin's Company , and when it's time to guide Frodo and the Fellowship, he has a much better understanding of how to deal with Hobbits and quests in general. Because that makes sense to me.
He also has the creepiest last line to Bilbo. Granted, Bilbo has outright lied to him for the first time, but still.
“You’re a very fine person, Mr. Baggins. And I’m very fond of you. But you are only quite a little fellow, in a wide world, after all.”
And the way his smile vanishes the minute Bilbo turns his back. Gahhhh! My sister and I looked at each other after that moment, and both of us shivered. Thank goodness we get back to Hobbiton and end with old Bilbo and a much less intimidating Gandalf, or I would have been permanently wigged out by our dear wizard. That parting of Bilbo and Gandalf in the woods at the Shire border at the end of The Battle of the Five Armies remains the part of all six movies that creeps me out the most. Never get on a wizard's bad side!
