This whole "retro" thing is pretty much a late 00s, early 10s fad that will probably be looked back on with a facepalm in about 7 years. Out with the Emos, in with the Hipsters... what's next? I can only anticipate with palm and face at the ready!
It appears the only way Instagram is any good to any one is if you get a bunch of OTHER apps and filters and make the pictures look better. Makes me wonder why even bother with Instagram if you can just use Facebook to upload 'filtered' pictures with the other apps.
