I like JCS as a stand-alone movie; but it's neither Biblical nor liturgical.  I enjoy performance dance, too, just not during the liturgy and, your right, No. 2 is not bad as dance goes.  If it were a stand-alone performance, I'd be OK with it.
Regarding No. 3: The title is that it is a 10:30 mass.  Besides the dance, the fact that "Strange Fruit" is played is off-putting.  It is a great song but it is in no way appropriate for the celebration of the Eucharist.  Looking at the rest of what this church posts on YouTube, it is likely that attending there would be an occasion of sin for me - at least I think that swearing at mass is still a sin.
