UK Arrow GAF checking in, seeing as Ep. 1 just aired here.
Great episode, and felt like it's taking a step back to good Arrow. Felt it handled a lot very differently to S3 would have.
For example, S3 would have had Diggle leave the team, unable to reconcile with Oliver, Thea would have been a wreck after having her brother and Roy leave, going lone-wolf and violently beating thugs up. Laurel would look longingly at a bottle of scotch, constantly in a mental battle to avoid the booze, Oliver would be having sleepless nights, forever haunted by his demons, and Felicity would be an emotional mess, torn between her love of Oliver and mourning the loss of Ray.
Instead, it handled it all kinda well; acknowledged where S3 ended, but dragged it by the horns to where it needs to be. They couldn't have just reinvented it all without a transitional period, but from the looks of Ep. 1, they're not messing about.
Didn't mind the flashback; it's always been obvious they'll fill in all the gaps until Oliver is back in Starling.
The flash forward though; I didn't mind it, it's an intriguing plot device and creates tension going forward, but man that was jarring. Fade to black and slowly fade in the "6 months later" or something, not just flash it up like that like it was cutting to the Arrow cave again or whatever. Weird choice in an otherwise good episode.
Fingers crossed it continues taking steps forward.
