That dictionary definition is no help to the discussion
You mean it's of no help to your case.
because it only gives a very bare interpretation of the word. In the real world "reminiscent" is used a variety of ways. In the way I'm using it I'm not talking about "oh here's a star destroyer that reminds me of the OT", I'm talking about the overall nature of the show and whether THAT is reminiscent of the OT. Which is the only meaningful sort of being reminiscent to discuss here. Who cares about little details, it's the overall nature of the thing that matters. And the overall nature of the show is NOT reminiscent of the OT. So the show is not reminiscent of the OT in any way that counts.
They aren't "little details", they're heavily reoccuring visuals in the series.
To imply that visuals aren't truly important is truly ludicrous.
Here's another to stew on: the Republic clones mounting attacks on Separatist ships is very reminiscent of the Battle of Yavin, in ways that the prequel "dogfights" never could be.
As such you can have all the star destroyers in common with the OT that you like but the show is still not meaningfully reminiscent of the OT. And the picture of a star destroyer certainly did not prove it was meaningfully reminiscent.
Continuing to deny that the striking similarities are meaningful is a type of stubborness that will quickly rob your opinion of any credibility it once had.
And I shouldn't have had to explain all that to you.
Don't make me laugh. ;)
