This week on home video, we’ve got a super successful space odyssey from Marvel, a feelgood sequel, and an inspirational sports film to lead things off. Then, there are a number of smaller releases, some notable TV box sets, and a few remastered anniversary Blu-rays of popular older films. Read on for details:

Guardians of the Galaxy

92%

Unless you were already into the comics scene, chances are you’d never heard of these so-called Guardians of the Galaxy. Boy, has that changed. The film surprised almost everyone by ruling the late summer box office, thanks to a number of factors: a cast of charming misfits, a wry sense of humor, top-notch special effects, a killer soundtrack, and James Gunn’s steady directorial hand. This is the movie that made Chris Pratt a star and put a dancing baby Groot on everyone’s stocking-stuffer wishlist. With a Tomatometer score of 90 percent and an Audience score of 94 percent, Marvel’s Guardians succeeded in impressing nearly everyone, which isn’t easy to do. If you pick this one up this week, you’ll get a pretty in-depth commentary track featuring James Gunn, a making-of featurette, and deleted and extended scenes, among other things.

Dolphin Tale 2

66%

Speaking of late summer surprises, 2011 had one of its own in Dolphin Tale, a feelgood movie about a handful of people rescuing a dolphin that was Certified Fresh at 82 percent. Naturally, we got a sequel this year, and though it didn’t fare as well as the first film, most critics found it pleasant enough. This time out, Winter the dolphin is struggling because her dolphin friend Panama has died; in an effort to raise Winter’s spirits and keep her at the aquarium, a search begins for a new companion to share Winter’s tank. Critics agree that Dolphin Tale 2 is a sweet, heartfelt drama for the whole family, even if it doesn’t quite distinguish itself from its predecessor, and it’s Fresh at 68 percent. Bonus features include a couple of short making-of docs, a look at Clearwater Marine Academy’s mission, and a brief piece covering the true events that inspired the film.

When the Game Stands Tall

20%

One of the reasons we love sports is that there are so many incredible stories to tell; the only problem is, when you’ve seen so many of them dramatized on screen, they become more difficult to distinguish from each other. When the Game Stands Tall suffers from this problem; although its tale of football coach Bob Ladouceur (Jim Caviezel) and the De La Salle High School team he led to a record-setting 151-game winning streak is undoubtedly remarkable, the film ultimately gets lost in all too familiar clichés. If you’re looking for something inspirational to watch, this may do the trick, but at 18 percent on the Tomatometer, don’t expect any surprises whatsoever, especially when the story plays out exactly like you might expect it to. Extras include a handful of deleted and extended scenes, a profile of the real Coah Ladouceur, and a look at the on-field filming techniques employed in the movie.
