A fine summary to Tengen Toppa Gurren Lagan series focusing on the most important (from the point of view of creators, of course) parts of it. Manly epicness, epic manliness, all that wrapped in flashy explosions and boing ... Yoko ... it sure brings back some (good) memories. The whole summary consists from two "stand-alone" movies - each somehow covering corresponding halves of the series. Because of that, some parts making the series more enjoyable are omitted (as well as few epic fights, mainly the fall of Teppelin that I really missed); still, this summary is good if you want to "re-watch" the show.
Nevertheless, summary is only a summary, so I don't replace the series by them - just a "friendly" advice.
