Yeah, I agree.
After all that build up from watching 7 episodes of Arrow leading up to this, and Oliver dies pretty much right away, his daughter resurrects him, then he BECOMES A GOD and it's like a total of 10 minutes of story? Years of that article that Iris wrote and those last two episodes of Flash (which I usually don't watch but did watch those) and Barry going through all this stuff, preparing to die - even the multiple moments he had with Iris in this ep thinking he might be saying goodbye and oop in 2 minutes everything is shifted over to another Barry and none of it meant anything. What a waste of time! None of it has had any payoff, and while I know it's not over yet it doesn't even feel satisfying. I'm not even dying for January 14th like I thought I'd be because everything is so over the top that they have no choice but to undo at least some of it. Bleh.
The fanservice is fun, but I don't know what half of these references are so I'm not even getting everything out of it that I could, LOL.
