For a teaser, the new Avengers: Infinity War trailer did the job for me, although some of the CGI seemed a bit dodgier than usual (Spider-Man, etc.). While I have yet to see the Justice League movie (I’ll have to wait for the home release at this point), I never did get a sense of a truly epic all-characters battle based on the previews. It seems/seemed “small,” particularly given what we already had with the previous Avengers movies, although I will admit that’s a high bar to meet. With this new teaser, I feel confident based on Marvel’s previous track record that we’ll get that kind of all-out conflict many of us dreamed of as kids (and frankly never thought we’d get with live action–thank you technological progress).
I think it’s fair to say the super hero thing is pretty much nailed these days. Frankly what I’d love to see now is a serious take on Dungeons & Dragons with the same budget/production values as your average blockbuster super hero movie. While there was the Lord of the Rings series, I still really want a true D&D experience (and Heroes of the Lance would do just fine in terms of actual characters to work with). It goes without saying that what’s been done to D&D in terms of movies and TV to this point has been a travesty, but then super hero movies used to be pretty bad in that regard as well, so there’s always hope.
