Starcrash is terrible, Tips, why would you waste your time watching bad films when there are so many good films out there?
Attack The Block, with its naff blokes in suits monsters and mangled pastiche of inner city patois (the Hi Hatz scenes just gave me flashbacks to the OG Loc missions from Grand Theft Auto: San Andreas) reminds me of the broad but well-intentioned stabs at creating genre films for the international market that Britain attempted in the 1980s-1990s while the VHS rental economic model was dominant. Films like Proteus, Hardware, Paperhouse, or Rawhead Rex, although the practical effects in some of those were probably better than those in ATB.
Despite the cheapness, some of the actual shots of the monsters are fantastic, particularly in the final chase sequence, and the matter-of-factness in the way they clumsily move about lends them a physical weight that still eludes even the best CGI, while I'm torn between thinking the glow in the dark Dracula fangs like you used to get on the cover of kids' comics before the EU decided they were too sharp or something - TAKE BACK CONTROL!!1! - are a genius visual gimmick, and thinking they're dead naff.
Actors are good, but John Boyega does nothing except glower and look handsome - I'm not gay or anything, but I probably would. Doctor Who is okay, and the rest of the cast is on the right side of the "annoying"/"not annoying" scale that kid actors should be.
More charming than it is good, but it's still pretty good.
