HR and Tracy, television GOLD right there... perfect chemistry and believable acting. As for the big reveal, which was a whole lotta nothing leading up to it by the way, meh. First off, yes it was obvious.. or at least all of the signs were clear and present from the very beginning. The thing is, Grant Gustin and friends told us, in no uncertain terms or parsing of words, that we would not see the true identity coming; that we would be utterly shocked by it. So that meant that it couldn't possibly be future Barry as that is the "duh" answer.
So what do they do... they reveal that it's future Barry. A cop out, sorry waste of a big bad reveal if ever there was one. Totally unimaginative and lazy. Now, they had better come up with the most insanely awesome explanation for Savitar's motives or I'm going to be one super pissed off fan.
