Funny for those with a sense of humor...
For all those overly serious folks out there, try to smile a bit more... and look around a bit more. If you don't have a good sense of humor or have nothing good to say then don't say anything at all. ;)
As for the film, I found it very humorous, as the people tricked into thinking something new was going to happen found quite the contrary had occurred... and thus wasted 'valuable time' sitting on their behinds waiting for the 'new release'...
