Yes, the movie is very underrated, indeed, and this really gets me down 
It wasn’t as succesful as (in my opinion) not-so-brilliant Madagascar or Kung-Fu Panda. It hasn’t gained so great popularity. And that’s a pity.
I haven’t read the entire thread because there’s too much of text. Maybe, I won’t say anything new. It seems to me that only one out of six people liked Wall-e. Among 12 men I know who watched Wall-e only two except me liked it very much. They were one of my best friends ZEUStiger and my 3-y.o. brother. Others either didn’t like it, or liked it but less than Ratatouille. I asked them about the reasons. Here they go.
My barberer liked Wall-e, but she told it was too scifi. Some of my friends claimed that the graphics was great except the peeps on the Axiom - ‘they could have been drawn more realistically’.
Some of you say that one of the reasons for so big ‘detest’ is a lack of dialogue. As for me, each dialogue, and the language overall has the only purpose - to help creatures share their thoughts about objects. Language is made in order to make communities of the peers, because if there is a language for each person, everybody will name the same thing in the different way and they will never understand each other. So, dialogue only helps to share opinions. If everything is clear without a dialogue, it is not necessary. Wall-e doesn’t need too much dialogue, imho.
For those who didn’t like ‘the Gels’. This is a cartoon. It resembles a movie, but it is still a cartoon, so it needs some cartoon characteristic features. If everything was designed in a realistic way, the movie would lose its points. The feeling of a cartoon soothens us and prepares us to receive something important.
The only reason I suppose to be true is the message. Most people have a lifestyle of a jerk, not caring about what is happening around him. They like their lifestyle and they decline everything that goes against it. The movie deals with that problems, and… so… no one likes to be punished.
I am writing that for you, because I want you to understand what I have understood. The message is very important, trust me. You should get it. Really.
Although I do not have any figurine of any WALL-E character, do not have the second disc and have no merchandise stuff (it is not sold here), I’m still a devoted fan of WALL-E and I love this movie. Each detail seems proper and apt to me…
Maybe I’m wrong, but Pixar seems not to worry about its box office. I hope I’m right. Thay were coining their idea of Wall-e for a long time and finally they have it implemented! I hope, it doesn’t bother them that the movie doesn’t seem to be so succesful as the others - they had a longing to make the world better, and they … did it… If even only one of you has changed a bit after watching WALL-E, this is a real success!
Thank you 
The only thing I didn’t really like were all the fat people, since I’m pretty fat myself. I’m not as fat as those people, but I was afraid someone would say ‘hey look, it’s you!’ xP Otherwise … I can understand why they’d be fat, considering the sort of lifestyle they lived.
I also didn’t like the idea of the earth dying without the people there - if people were gone, Mother Nature would take back what was rightfully hers in the first place - but since the humans sorta poisoned the world with all their chemicals and crud, I can understand why it’d need the humans help to come back.
Well, there were people I know who said WALL-E was okay, because the characters were pretty lovable, but they are just used to more dialogue in movies, that’s all. There’s this one guy who said he’s not into movies or anything that doesn’t have dialogue, and he did not like WALL-E, personally, because it mostly lacked what he was looking for.
Yes, the soothing in this movie is important to provide optimism against the ruined world and open up one’s mind to all the troubles and solutions. Since the movie doesn’t play the blame game, everyone comes away with only a little guilt.
By next summer probably 100 million people will have seen this movie. The people at Pixar are indeed concerned about the bottom line (money), it’s their job. But they have often said that they do movies that they like to make, this means originality, high quality and polish, and pictures that will be seen by kids and families who demand action, comedy and value for their 10 dollars. The ‘schlockmeisters’ may croon about Madagascar2 (which is only a decent animated feature, certainly better than real ‘schlock’) as the ‘cream of the crop’ to such a viewer. -Sorry, these idioms may be a bit difficult to understand for a non-native English speaker.- But no matter how much those people crooned over Mad2 or Hellboy2, our cultural intelligentsia and even the masses voted Wall-E a smash blockbuster movie, exceeded only by 3 extraordinarily well-known franchises: Batman, Iron Man, and Indiana Jones. And only the Batman exceeded our friend when it came to dvd sales.
