Doesn't look very promising. For high cost iMax, the sets strike me as low budget TV. The trailer makes it appear that Maximus (Iwan Rheon) will have 90% of the dialogue. He's OK at set chewing, but I don't take him seriously as an actor. Kind of one dimensional since his stint in "Misfits." Medusa's hair is remarkably flat and lifeless. I would agree that the bulk of the budget seemed to go into the Lockjaw CGI.
Madusa annoys me the most, how hard/expensive would it be to always have the hair moving a bit??
Yep: Lockjaw good; Medusa's hair bad; silent main protagonist?
Hard sell.
