It does look good, but also pretty generic. Awkward teenager gets a superpower, cant control it, wacky situation, bad guys arrive, now he develops self-esteem, controls his power and saves the day.
The blue beetle powers are not that interesting or not interesting enough that i would watch the movie in cinemas. Sword is honestly just boring, i would like the idea more that the scarab has only defend powers and he needs to rethink them/use them cleverly.
