The My Dearest franchise is not something you need to be aware of

This is a snapshot from the Wikipedia page devoted to Netflix original films. 

If you saw a little more of the snapshot, you'd see that the first is Spanish and the second is Thai. So, no relation.

I do think it's funny that Netflix should have randomly acquired, and decided to release, two such similarly titled films in such close succession. It does, however, appear just to be random.

But I wouldn't put it past Netflix to imply a relationship, maybe even a recommendation. "If you liked My Dearest Senorita, you're sure to like My Dearest Assassin."

Maybe I'll watch both of them just to find out.
