There are a couple of B-noir movies--Shack Out on 101 comes to mind--that sometimes entertain with their low-budgetness. Sometimes, like in Detour, they absoltely shine.
Accomplice has a good, writerly story in there somewhere. I gather from the credits it's from some serial novel about a private detective. But the writerly touches are so buried in the low budget and crummy acting that it's hard to find it. Still--it flashes through sometimes. An eccentric desert castle for the denouement. A detective who loves old books and Jesse James mythology. Some cool location shots in Lancaster. Chase scenes along Route 66. Some potentially interesting flirtation between old lovers and new lovers.
But it never comes together as the movie races along (only 60 minutes!) and the actors try to find the camera. There's also a great blooper where the lead PI ends a scene forgetting his line: "Better take your sleeping pills, it's a long way to....(pause) uh...." CUT.
Guess they missed that one in the editing room. Nonetheless, some lowbudget guilty fun, highlighting the thing line between bad/good and just bad/bad.
