Not satisfying enough.. Also maybe a plot hole?

Rating: 6/10 (27 April 2019)

The ending scene was very enjoyable.. The cg and vfx were great but..
A lot of Fan Service and childish humor.
It tried but it couldn't be better than infinity war.
In my opinion I think the movie could have been about 90m long.
The plot hole that I think I found is..
Sorry I don't remember names..
But in the scene were neboula and the Ironman suit guy took the blue infinity stone.
When they tried to warp back neboula got stuck and synchronized with the other neboula.
After thanos learned what is going on..
And neboula got desynchronized why she run until the spaceship to call the others and not just warp back and then tell them what is going on.
She could have escaped being kidnapped..
If I didn't understood this part just ignore it.
