Feige was 16ish when Keaton's first Batman came out, so seeing him reprise the role was probably something he's looking forward to.
Yep, the first Raimi Spider-Man came out on my 15th birthday and I saw it with a bunch of friends in the theater. I waited a few extra months to watch NWH specifically so I could save it for my 35th birthday.
Seeing Tobey suit up again 20 years later to the day was such a cool way to celebrate. I've heard people talk about movies making them feel like kids again but that was the first time I actually felt it myself.
So I feel horrible for anyone that was looking forward to a similar experience with Keaton's Batman coming back. Talk about having the rug pulled out from under you.
