There are echoes of early Smallville with the "freak of the week" formula (likely an unavoidable trope at this stage), but at least this episode addresses a key concern I had; What do we do with these villains? You can't put them in a conventional prison, and you can't just kill them all. This week's freak is a bit weak (rhyme time!) and underdeveloped, and I'm starting to wonder why all of these metahumans (save for Barry) are evil so far, though I concede it could be part of Dr. Wells' elaborate (and to me at least, as someone not familiar with Flash canon) mysterious plan.
But the strength of the show remains the very human relationships between the characters. None of the pseudoscientific mumbo jumbo means anything unless we care about the people who inhabit this universe, and here I do. I particularly like the use of flashbacks to flesh out the various backstories, and so far at least, it's all tied in nicely with the story at hand.
I would like to eventually see The Flash develop a rogue's gallery. See some sort of larger threat. But for now, that mastermind remains hiding in plain sight. But as long as they continue to find the heart beating beneath the costume, I'm game.
