Awful. Simply Awful.
I knew I was in for a mess when the film started with George Clooney talking into the camera and participating in "funny" banter with a young girl. First place, having a "narrator" to tell the story to the audience is lazy storytelling.
Then we go back to Frank as a little boy and he somehow enters this Tomorrowland world which makes absolutely no sense. It is just 15 minutes of Disney SFX. Nothing more.
Then we jump to 2003 and meet the girl Casey. And then she somehow is transported to Tomorrowland where we get another 15 minute "tour" of the future with all of these SFX but really no story telling.
Then we return to 2003 where the movie becomes a "and now this happens, oh and now let's have THIS happen" but nothing that happens is related to anything that happened before and most of the things that happen make no sense. Casey has here little brother tell her dad that she is going camping for a few days? REALLY? No parent would EVER be ok with that. But the writers had to answer the question, "Why don't her parents look for her?" The robot girl (Athena?) drops Casey off at Frank's house where she stays for a day and they get chased around by evil terminator type robots. Then Athena comes by in the truck and picks them up. Why didn't she just pick up Frank when she brought Casey there? Nothing in this movie makes any sense it just jumps from this setup to this setup to this setup to...and it goes on and on and on.
The only reason Clooney did this movie was because its preachy message appealed to him.
