Everything that you’ve heard about Daniel Day-Lewis’ stellar performance in “There Will Be Blood” is accurate. What isn’t often mentioned, though, is that his character Daniel Plainview is a vile, greedy and nearly inhuman oil tycoon who will do anything — even murder — to get what he wants. The story isn’t that strong or complex: Plainview has a son whom he finds a burden; his rival is a local preacher. The score sometimes tears the film apart; the music is awkward and out of place. The story line, too, loses focus quite a few times. Still, the movie’s worth checking out for Day-Lewis’ Oscar-winning performance. The set’s second disc includes information about the oil industry in the 1920s, including “The Story of Petroleum,” a silent film from the era. Price: $34.99. Rent or buy: Rent.

The pair’s bond doesn’t break, even though the creature grows to mammoth proportions. Special features include six detailed behind-the-scenes featurettes and deleted scenes. Both the widescreen and full-screen versions are in this set. The Blu-ray edition includes a video game. Price: $28.96 to $38.96. Rent or buy: Families ought to buy.

Robert Redford, Bette Davis, Burt Reynolds, James Coburn, Barbara Bain and Adam West are among the notable guest stars.

ROCK OF LOVE — THE COMPLETE FIRST SEASON

VH1 has cornered the market on rockers-in-search-of-love reality shows with “Flavor of Love” and “Rock of Love.” (Call them low-brow versions of “The Bachelor.”) “Rock of Love” has former Poison lead singer Bret Michaels trying to find a mate from a selection of 25 scantily-clad women. While it won’t win any achievement awards, the show, now in its second season, is a guilty pleasure. This set includes 13 episodes with new bonus footage. Price: $34.97. Rent or buy: Rent.

Other DVDs debuting Tuesday: “The Dream Factory — Volume 3,” “Teenage Mutant Ninja Turtles — Season 6,” “The Final Season,” “The Adventures of Baron Munchausen,” “Music Within,” “Walk Hard — The Dewey Cox Story,” “Tilt” and “Lions for Lambs.”
