Online sensation the ALS Ice Bucket Challenge is now the hottest thing this summer with Hollywood celebrities taking part and spreading the love to pledge in fighting ALS around the world. But some are not too happy with the success of the virtual chain letter with other charities claiming that the pop phenomenon is taking donations away from them, while others just had an epic fail while doing the challenge.

Celebrities and non-celebrities alike are doing their share in spreading the cold water shower all for a good cause, and just this week the Ice Bucket Challenge craze are building to its all-time high raising millions of dollars for the charity. More than 13 million dollars have been pledged and still counting, which is more than eight times they received last year.

"Critics of the social media campaign are also blasting the challenge because it's a waste of water, but those critics are singling out those in California, who are currently experiencing a drought. But there are those who think it's wasteful, regardless of your location," reports E! News.

Also known as Motor Neurone Disease in the UK, the fight for Amyotrophic Lateral Sclerosis (ALS) was kick started by the ALS association. The cool challenge went viral when a bunch of professional golfers encouraged their fans to take the dare while nominating three more people or donate to their favorite ALS charities.

But some people took the dare and bathe in cold water, and still donate some money for the fundraising campaign, a selfish act to raise awareness while having fun at the same time. Former "Two and a Half Men" star Charlie Sheen even made a statement by pouring money on himself to represent how much money he is going to donate.

But even with its popularity, a lot of people are claiming that the dare is sort of campaign "slacktivism," which means that the ALS Ice Bucket Challenge allows people to show support without doing really doing anything.

"A lot of the participants are probably spending more money on bagged ice than on ALS research," according to Slate's Will Oremus. "As for 'raising awareness,' few of the videos I've seen contain any substantive information about the disease, why the money is needed, or how it will be used. More than anything else, the ice bucket videos feel like an exercise in raising awareness of one's own zaniness, altruism, and/or attractiveness in a wet T-shirt."

Celebrities who joined the challenge include "Fault In Our Stars" heartthrob Ansel Elgort, "Arrows" Stephen Amell, Microsoft's Bill Gates, "Baby" singer Justin Bieber and "Guardians of the Galaxy" star Chris Pratt.
