Yes, you're right, starting your videos with the same title isn't very valuable from an SEO perspective nor a click-through perspective. Definitely remove that and go with a title that just teases the video.
Regarding clickbait, asking questions doesn't usually attract as many views as taking a stance on something even if it's controversial. A better title than, "Is Fifty Shades of Grey Abusive?" is, "7 Reasons why Fifty Shades of Grey is Abusive," or, "Fifty Shades of Grey Is Abusive. Here's why." I think you could still come up with some better titles than that, but just to go along with your example, you get the idea. Use questions in your titles if you're actually genuinely exploring a question that you don't have the ability to take a stance on. Like, my video today is, "Wait, Facebook Video Monetization might be Coming?" That's because I honestly don't know if it's coming or not nor is there a way for me to find out or even take a stance one way or another. I added the, "Wait," part to make it feel more like a surprise kind of thing.
Dunno if that helps or not, but there ya go.
