Where did the map lead?

It says it in the movie. Its to the first Jedi temple. Han states that's where those who knew Luke best think he went, and this was clarified by Pablo, It's not a mystery at all.

 

I don't recall anyone saying the map leads to the temple. I'm pretty sure they say the map leads to Luke (who was looking for the first Jedi temple).

 

OMG lazy writing!
Why should I have to piece anything together!
It should all just be explained with exposition dialogue that bores people!

Don't you worry, you're not alone in feeling puzzled about the map.

The part that I think was made pretty clear in the movie is that the map leads to Luke. So far so good. However, what bothered me, you apparentely, and I suspect many others, was not understanding why did the Empire archives were incomplete, but more importantly what does the red path actually mean? Is it the path to find Luke, or the path to find the first Jedi Temple? If it's the latter, then there would be a chance that Luke was not actually there, because after all only "some who knew him best think he was heading to find the first Jedi Temple". So, what makes everybody assume(the viewer included) that Luke will actually be there? Or perhaps that was always the intention, to make it unclear if he was there or not. Perhaps only a lead would be found there? But, Kylo, Snoke, Leia, others all seem to be sure he will be there. Something doesn't really seem to add up, as you pointed out.

Some say the red path is Luke's trajectory while looking for the first Jedi Temple, and that it got recorded somehow in R2's piece and the empire's? Doesn't make much sense does it? The other idea, the consensus apparentely, is that the map leads to the first jedi temple. That somehow someone erased the final section so that it would not be possible for anyone outside a small circle to know about its whereabouts. But why? Was it Luke himself that erased the section from the empire's archives and gave the missing piece to Lor San Tekka, so that he could hide himself there until "the time comes"? Is the temple important for Snoke, or just Luke? How were Kylo and Snoke so sure Luke would be there?

So, I guess we had to connect the dots for ourselves. If course, understanding this while leaving the cinema after the first viewing is almost impossible, or at least only at the reach of the more illuminated minds.

No, it's not clear at all what the map significance really is. Perhaps that's part of the mystery, to be solved in the next installments, or perhaps the writing didn't come across as best as the writers hoped. Thanks for giving me the opportunity to take this out of my chest
