The first film,
Gurren Lagann The Movie: Childhood's End is basically a compilation of the first half of the series with things cut out to fit the duration (1 hour, 50 mins) while the second film,
Gurren Lagann The Movie: The Lights in the Sky are Stars is a 2 hours, 5 min compilation of the second half again with a few things cut out but some new scenes as well. The
Parallel Works are some short music videos with some quirky animation, around an hour in total. I like shorts so I enjoyed them.
There's was a few video issues. Basically the master they received had some video missing so they spliced in the DVD footage. The affcted episodes:
Episode 5 @ 20:47 - 20:56
Episode 7 @ 8:29 - 8:42
Episode 10 @ 17:27
£18 is a fantastic price for the series which is pretty much the full experiences sans the films. I think that they might sell the films by themselves on BD down the line, but those plans might have changed.
