I know that many others felt the same way especially for those unfamiliar with Michael Keaton such was the case when living in Ecuador at the time I don't think he made a lasting impression like Superman with Chirstopher Reeve.
The thing that makes Keaton different than Reeve, is that Keaton left after two movies (wisely so, but still).
In the states at least, Reeve is considered THE Superman, whereas Batman is known for having a revolving door of actors and directors. Not to mention, Adam West's fame is much more overshadowing than George Reeves'.
At the time B89/BR were new, however, Keaton very much WAS Batman in the public consciousness. You can tell from the bevy of references and appearances in the media at the time. Even Tiny Toons was referencing Keaton as Batman.
