Ehhhhh..... The frequent time jumping stuff that would even be the entire point of using them works better through episodes of a series, imo, and may be harder to incorporate into a film with a solid story. If a show spends 10 min in a medieval period, so be it; if a film does it...what was even the point, it wasn't even long enough to really enjoy that part or make it mean anything.
Savante Romero might also require an awful lot of time given to backstory so that uneducated viewers even
get what he's about, rather than offering no info on the confusing situation of why it looks like the devil is traversing time and fighting the Turtles. Then add in Renet's needed backstory as well to explain what this odd ditzy woman has to do with it and why she isn't just some normal Earth person involved for an unknown reason.
That said, taken from Savante looking and being kind of demonic... now I want a Turtles vs The Underworld.
