FLAME ON~!
A Marvel Comics theme with the long(ish) Across fills referring to the "super-powers" of the four members of the reveal "Fantastic" group - here's the Wiki.
I must apologize in advance to everyone here at the blog who is a
massive comic book and/or Marvel / DC Comics movies fan - it's just not my
"THING" (get it~?) I grew up with Star Wars, and those movies, toys
& action figures. I did actually see the Fantastic Four movie
released in 2005 ,
but the "THING" I don't much care for is the never-ending
"remakes" and rebranding of comic book superheroes - including Batman, Iron Man, Spiderman, etc.
- Fantastic Four came out again in 2015 ( and for the truly hard-core,
there was a 1994 movie as well ). The "THING" is, part of the reason
for my apathy - and this is a consequence of Star Wars - is that the
movies are SO overdone with CGI that it's all just a blur to me....
