What’s particularly egregious is that Poe and Holdo’s plan basically end up being the same. They both end up sacrificing massive numbers of rebels/ships to achieve a goal. The major difference is Poe’s plan is proactive and achieves something while Holdo’s is passive, hide, hope the enemy won’t notice and someone else shows up to help them. The thing is her plan would have failed no matter what because the very first Star Wars movie established that star destroyers can and do track escape pods, right down to being able to tell how many people are abroad.
The other thing that is ignored is that Poe’s entire squadron ignores Leia’s orders. It’s not like he even ordered them to. They clearly thought their goal was important enough to keep going despite being ordered by a general to turn back. (Plus they would have still been getting slaughtered while they retreated so everyone would have died for nothing).
Really the main problem with Poe’s plan is that it’s mired in conventional air combat, which doesn’t make any sense especially when TFA established that it doesn’t have to be.
