Well for a second or third tier dc hero, guess it's reasonable for what it is as a film. The biggest role that I can remember Shazam did on the dc books was Kingdom Come and maybe a part of the Flashpoint storyline. Tonally it has the vibe of 80's Big and Goonies. Wish fulfilment of kids running their smart ass mouth. All in all they did good on the Shazam's family aspect and might synergize with a rumoured 2019 relaunch by Geoff Johns.

It is not by any means a good movie as in, still got a villain problem and like WW where you need to ignore the shortcomings and just enjoy what it is. The heart and charming cast members simply connect with the audience. At the bare minimum now you can't fathom anybody but Zachary Levi is "the" actor for Shazam.

The big takeaway for me is DC able to bring lesser known heroes to the screen. This will certainly ease audience into the rich catalogue of smaller characters. Now they just need to deliver a through and through comic book movie experience on the level of Dark Knight, Logan, Spider-verse.
