Same general order.
'89 & Returns - i like these almost equally, though with just a slight edge to Returns. They share 1st place in this series for me.
+: Keaton, Burton, Elfman, the look, the music/score, the car.
Original movie poster for '89 - Batsymbol & the date. Done, sold.
The opening sequence of '89 where it traces the symbol to the Elfman theme.
The opening action sequence of Returns.
-: Batman's body count in both. Killing off the main villains.
* And, like everyone else on the planet, when it was learned who was cast as BW/Batman my response was "Keaton? Really??"
At that point I'd only seen him in two or three things. And even though one of those was Beetlejuice I'd not have thought of him dressed in the bat suit.
But good choice.
Other than Adam West he's my favorite live-action Batman to date.
Forever - eh, its ok. Not as good as Keaton's outings, but....
+: other than the two main villains I liked most of it well enough. Or didn't dislike it.
I even sort of like the car..
-: the villains. Neither of these guys are {my} favorites from the comics, but i can see using them in a movie. Jones & Carey were utterly wasted in these roles however.
Batman & Robin.....

+: the coolest thing about this movie was its intital teaser/trailer. The one where you see a snowy Gotham & the camera slowly pulls back to reveal Mr. Freeze holding a Gotham snow globe.
-: Of all the merchandising for this one (and there was alot)? They never sold the damned Gotham snow globe.

- -: Gah! What the #&$#* did they do to the car??
