If you actually bothered to read the OP, they actually let the OP watch his valuable cutscenes until the last fight before kicking because he did not contribute much to the completion of the dungeon. He even admitted himself with this jewel right here:
At least the players in his group allowed him to watch the cutscenes all the way TO THE END before kicking. The OP is overreacting and being a kid really. It's a lower level of frustrating similar to having someone in the group fall off titan right at the start and claiming loot at the end of the fight.
1. OP got to watch his cutscenes, all the way till the end.
2. OP ignored the other players asking him to not watch cutscenes, so they responded in kind by not wasting their own time and going ahead with fights.
3. OP is unhappy he got kicked because he did not contribute enough to the completion of the dungeon.
It's almost as if you players on the EN servers don't wish to complete content when you queue for the DF. DF has one purpose and one purpose only, which is to help you form a group from a bigger pool of players from different servers to aid in the completion of said content. Obvious with this being an MMO, your time < their time and their time < your time. Your time = their time. Watch cutscenes if you will, if your party is nice, they'll let you watch it. If your party is even nicer, they'll let you get a free ride to complete the dungeon with you doing nothing at all right till the end other than watching cutscenes. Else, it's either a kick at the start(this is the worst case obviously) or kick at the end(where you actually got to view ALL the cutscenes up till the final boss).
Now, if the new player was only wanting to go in to view the cutscenes for their first time for the immersion, he already got his goal as he got to watch the cutscenes uninterrupted. The next time he goes in, assuming he got kicked like the OP in the previous run, he can actually skip the cutscenes now and do the battles for the other part of immersion.
tl;dr you can't have your cake and eat it too.
