TV Version. As a huge fan of this movie, fascinating. The cuts can be awkward, but the new scenes are all pretty good. There's more of peripheral figures like Nic Cage, Eric Stoltz and Anthony Edwards. Losing quite a lot of Phoebe Cates' material effects the balance of the film though. It's, oddly, a little less playful in this version.
A worthwhile curio, and something I'll probably rewatch for the extra moments, but the original is obviously the definitive version.
The original gets 5 stars. This gets 4.
