Well, as always, there is a love interest, and that's the overused Zooey Deschanel, who plays Happy. She comes down to the mattress store after her father (John Goodman) decides to buy an expensive Swedish mattress. A relationship begins. The odd thing is, there's no real energy. The same thing can be said for the movie. It feels oddly weary, and, in a way, drug-induced. There are a lot of plot elements that seem to have little or no effect on the film. Such as the random attacking or the studies of rats that Brian's alcoholic friend from college (Brian Avers) conducts (I suppose these exist so that there can be poor similarities drawn between rodent and homo sapian). Not to say the film is all for nothing. I'm not sure the name of the character or the actor, but there's a good performance given by Brian's meditating mattress co-worker. He supplies the only life into the film, delivering offbeat lines with a nice ease. There's not much else here.
Dano is all over the place, and Deschanel is lukewarm playing two notes: quirky girlfriend a la "(500) Days of Summer" and self-effacing girlfriend. Goodman does moderately well in a comic part as one father. The same cannot be said for Ed Asner, as Brian's old, conventional-thinking father, at least as the film fails and caves in at the end (a fellow moviegoer noted his awfulness and I think he wasn't very good either). Mary Page Keller as Happy's estranged mother delivers another standout terrible performance. I dunno. I guess nothing could have really solved Aselton's problems here. Here's a slipshod, fragmented romantic comedy that does not work save for a couple of bits. "Gigantic" (poorly-titled to say the least) is not gigantic in terms of influence on anything. The title describes only the drawbacks in Aselton's poor movie. D+
