I guess I see what you're saying, but the thought never crossed my mind. On that superficial level, sure they're similar. But the themes of the films are so different, the tone is so different, the characters are so different, that I still can't imagine TDW as a mini-Avengers.
And just a comment on the exchange above (sorry to butt in, and I'm not trying to attack you or anything): I can tell that you love the MCU because you are very passionate about it, but there seems to be just a negative tinge to a lot of your comments, which gives people the wrong impression. Everyone sees the world in a different way, and you're entitled to your worldview, but when so many of your comments are framed in such a way, it really gives the appearance that you're being intentionally negative. Were you the one who started the "Will Surtur Suck?" thread? Why not just a general Surtur thread? Or "What is the best way to do Surtur" or something like that? Again, sorry to go on like this. It really isn't my place to say anything, so if this post bothers you and you want me to delete it, let me know. No harm intended.
