Rarely do you get as much media attention to a movie having a disappointing opening as you do with Tomorrowland.
As I noted before, it's been absolutely clear from looking at comments at American sites in particular that Clooney is despised by those on the Right for his liberal stance, and when someone like Drudge calls on the Tea Party's flying monkeys, they are happy to visit any site (Variety! - ha) with comments rubbishing him and any movie he's in. (Disney itself is somewhat of a target too. I'm not sure that any truly dedicated Tea Partier in America can bear to go to one of its theme parks.)
Of course, it's true that the movie has received mostly mixed reviews. But at IMDB, it's receiving a user rating of 6.9, which shows most people don't consider it a complete disaster.
The political getting involved in attitudes towards movies reminds me of John Carter in 2012. I recall that, for some reason, Right wing sites tended to give it good reviews, but it was a genuine box office disaster - $73 million in the US in total. When it turned up on free to air TV here sometime last year, I tried to watch it, but man, it was awful, and I gave up after 30 minutes. I have no idea what make the Right side with it.
In any event, my allegiance to Brad Bird will ensure I see Tomorrowland this weekend. (I think Clooney is likeable, especially in comedies, but I don't by any means see all of his movies.)
Update: for those who note that I can't stand Clint Eastwood - true, I can't, although I don't just put it down to his dopey politics (the empty chair routine helped Obama, if anything). I have always found him a bad actor, don't care for his frequently recurring violence and revenge/vigilante themes, and never thought any of his films were interestingly directed. And besides - he has wide respect even from notoriously liberal American film critics (see Sniper, for example), showing that (unlike the Right) the Left does not automatically write off Hollywood figures because of their politics.
