That said, I think the real problem with Discovery so far -- the writing -- transcends the setting. If they keep trotting out threadbare Trek tropes, it doesn't matter if the show is set in the 23rd, 24th or 42nd century.
I actually disagree with the tropes, of course, it depends on what trope we're talking about here. I'm more forgiving to a series like Enterprise having a transporter malfunction because it's a newer technology with regard to the period it's set in. It's the fact that this particular trope was first introduced to us on a series that takes place a century after Enterprise. So, it makes you wonder, why are they still having trouble with a 100+-year-old technology?
The timeloop episode I thought worked because even though we've seen it happen before, it wasn't as if it was some phenomenon the Discovery encountered; it was something being done to them dliberately by someone. So it took a trope and, in my opinion, gave it a fresh spin. To me, it's how it is introduced and how is it solved that make it fresh.
Name some other tropes that Discovery has fallen back on, please.
