The trailer looks promising. Caspian was a big disappointment. Hopefully, this next installment will be better.
Honestly, Caspian was the weakest of the books IMHO. Not surprised it didn’t translate well, whether they tried to juice it up or no.
Dawn Treader is much, much stronger. Not much of a main overall conflict, but lots of smaller conflicts and great settings and scenes, including Eustaces conversion, will overcome that (I hope).
