When Glenn Morshower debuted the Arrowverse verison of General Sam Lane, father to Lois and Lucy, on Supergirl, the character was pretty true to how he had traditionally been depicted in the comics. With a conflicted relationship with his daughters, Sam was married to the military, deeply suspicious of aliens in general and of Superman in particular and, generally speaking, one step removed from being Thunderbolt Ross. And that's not to suggest that the Arrowverse was setting out to copy Marvel; rather, that take on the character is pretty well in line with what Sam has been like in the comics since, basically, the mid-'80s when he came out of Crisis on Infinite Earths reinvented as a military man rather than a horse farmer.
