Just saw the beginning of the new series.. so far I've seen one 'homage' appearance. The OLD flash is Berry's dad..
10 minutes in and I like the teaser. Hoping they don't fall into the 'smallville freak of the week' hole the first season..
They have said there's quiet a number of characters that need introducing in the first episodes so the first part of the season is going to be more of an ensemble\anthology type thing, so not all Barry all the time.
But I think they might go 'Freak of the Week' for a while just to get Central City and Team Flash established, and there's a lot to squeeze in. Vibe, Killer Frost, Captain Boomerang, Firestorm, Gorilla Grodd and those are just the ones we know about.
