Dude don't bother, I've been trying to say that for ages but for some people nothing is enough, it's best to let people think what they want to think because you'll just end up arguing in circles, believe me!
The fact is the film is a certified box office hit however it could have had better legs and made more had it been a better film (I thought it was a solid film IMO). But like another poster put it so aptly in order to go up against disney in 2015 you'll need superman and batman because neither of them are gonna cut it against films like averager or star wars or even finding nemo 2 (the original was a monster hit and it wouldn't surprise me if that film could end as one of 2015's biggest earners).
I have to admit it is the logical decision, even though I don't like it at all. MOS was a hit but its legs were so weak, which implies that many people didn't like it, though the majority did. However, WF can only compete with Avengers and Star Wars if it is a strong movie that has much better WOM than MOS, and much more importantly, better WOM than Star Wars and Avengers 2. Otherwise it will just open big and crash like MOS. Whedon and Abrams are both much better storytellers than Snyder IMO, so I suppose I can only expect the worst and hope for the best.
