This. Smash 4's opening was promising at first when they started showing the original cast's intros and what they do in their worlds, un-reused CGI and all except for a few, but after that, just random clips galore. Which makes me think, what happened to the actual CGI character intro's like link weilding his sword in the air and vilager getting his smash invitation? Would've been more fitting.
Also, I don't get a sense of closure or purpose with this opening unlike 64, Melee or even Brawl. With 64 and Melee, they show you that Master hand makes the world while pinning these toys forcefully which is why all these characters come full circle to stop him (also with a preview of pre Giga Bowser in melee's case). Brawl, despite it's opening being a bunch of clips too, at least shows that the Smash World is being eaten up by the SSE.
What's Smash 4 about? The visuals are impressive and it's a nice little opening but random clips of multiplayer and the classic gaming mascots tells me nothing.
So with that, imo I'll have to give Melee 1st, SSB64 2nd, Brawl 3rd, and Smash 4 4th.
