The only fan service in R1 that stood out as pointless was those two guys from the cantina.
I agree. This was the only one that really jumped out at me. Other stuff like the blue milk and the little "radio controlled car" imperial droid (I'm sure somebody knows the name
) were nice touches, but not overdone.
The scene with R2 and 3-PO was a kind of blink and you'll miss it thing, and didn't really bother me.
If they wanted to lean more heavily on fan service, they could have given Vader a lot more screen time. I'm glad they didn't, but one or two more short scenes would have been cool.
I'd like to see the deleted scene that we got a glimpse of in the trailer, where Krennic says "The power we're dealing with is immeasurable". It would be cool to find out how that whole thing played out.
