Honestly I feel like they're just complaining to complain. I'm all for pointing out flaws and sure, I would have liked it if crazy Barry was strung out for a few more episodes– but it's the first episode. We don't know if Barry is 100% normal again or what those symbols mean. For all we know the minute Barry sees the symbols he'll relapse or something and go back to spouting nonsense.
They have 22 more episodes to flesh out the story and explain everything. People need to relax.
