This is the opinion of someone who is sour on Star Wars these days because of the oversaturation and spoiler habits, but someone who enjoyed the original trilogy, and enjoyed Han Solo as played by Harrison Ford.
That's not Han Solo, that's not Harrison Ford, maybe an impersonation of Han, an interpretation more like it, but is that even an impersonation of Ford? Hell no. I'm being harsh in the judgement because it's a trailer, but through the stuff I read implying that even Disney knows this will bomb, I just have no hopes for this. It looks like something generic, I didn't get much of a Star Wars vibe other than the little remix of the main theme. Even the colors threw me off, maybe going for Rogue One, but it's like it had an overcoat of gray, which is not appealing. One movie that had that overcoat and became a huge issue for me, Man of Steel. So, yeah, not interested. I'm sorry for Ron Howard.
