Several thoughts:

1. Disappointed when clicking the title at first that this wasn't a tribute to Conan O'Brien.
2. Slightly less disappointed on seeing this was for a Pixar movie.
3. Watch the trailer with reservation since Pixar has not made anything great since Inside Out in 2015 (admittedly not that long ago) and before that Toy Story 3 in 2010 (much longer ago).
4. Cool to see a Latino protagonist, so far so good.
5. Movie has something to do with ghosts. Also good.

Looks like this could be legit.
