I'm glad you liked it man, not trying to be a hater but just had to be honest about how I felt. I'm still really looking forward to the movie and hoping for the best. I'm sure Keaton himself is going to be great, it's just a question of how the movie presents him that has me a bit unsure right now. Seeing him in broad daylight was weird for me....it's possible it could be a "good weird" once I see the movie but I'm just unsure right now. I'm okay with it being a bit campy, but like you said I think the visual aspect of it is a bit iffy for me right now and that's my main issue.
I think you're in the majority as the reaction seems to be great and I think the movie has the potential to be a huge hit and win for DC. For Keaton's sake alone, I'm rooting for this movie regardless of how I end up feeling about it.
