I think I overhyped this movie too much for myself...It was great but not as good as I thought...I WILL see it again and I think it will grow on me, the more I watch it.
Yeah, I had a similar reaction myself the first time around. After the first time seeing it, I realized that I didn't really come out WOW-ed like I had for most of the other Pixar films, but at the same time, something was bugging me to see this movie again. For starters, I had extraneous circumstances that were really keeping me from enjoying it this first time around, like noisy kids and being on standby at work (meaning they could call me out at any time - it was nagging me that entire week).
Plus, a very similar circumstance happened to me with the Incredibles - thought it was alright the first time, LOVED IT the second time.
So weeks later, after all that mess went away and the crowds started thinning, I went to see Wall-E a second time. MUCH MUCH better. Still not quite my favorite Pixar film, but that's obviously not a knock on it in the least. It just has such incredible competition!
Incredibly charming and amazing with the visuals. A lot smarter than I perceived it to be the first time around, also. Plus, I saw a bit of myself in the Wall-E character/situation too (sad to say), which helped to make it a bit more personally moving.

Without question, the scene towards the end where Eve finally takes Wall-E's hand was (to me, of course) one of the most touching moments I've seen on film in a while. To put it in a Pixar perspective, it was right up there with the final scene in Monster's Inc., where Sully finally gets to see Boo one more time.
So after having a quieter environment and no extra baggage, the experience was definitely a lot more satisfying this time for me. I thoroughly recommend seeing it again, for those who were kinda on the fence the first time like I was.
