You can hear at least one engine running before it touches the ground AND you can see that the plane is at least in somewhat in control, considering it lines up with the runway properly and does a flare AND a thrust reverser is active before it hits the ground.
The control surfaces work without power (with great effort) since they are mechanically linked in the case of emergency on the 737 NG. If the gears were down, it should have triggered automatic flaps to slow the plane down on touchdown.
None of this makes sense, unless we assume the pilots royally fucked up basically everything. They missed the optimal landing point and only used about 40% of the runway traveling at what appears to be at least 80 knots above the normal max landing speed.
