Yeah, pretty sure it was.
I think the fans wanted it to be epic and they asked the makers before it was released if it had epic scale considering Thor in the comics has some pretty amazing storylines that certainly are "epic" and the makers didn't deny that it was or downplay the notion.
They mentioned that you would see many of the nine realms etc., etc.
And most sequels try to outdo the first movie in scale and I'm not sure if TDW did that.
Then the run time came in at 112 -- the then (and current) shortest MCU movie and the fans started to doubt it.
Of course in many fans opinions the biggest fault of TDW isn't it's scale but the inclusion of the Earth characters in a story where they weren't needed.
I like both the previous 2 Thor movies a lot but I am glad that this one looks to be the biggest one yet with lots of new settings and characters.
