You're missing the point. Under the DMCA, the service provider doesn't get to make that judgment. If it receives a notice that complies with the bare requirements of the law, it must remove the allegedly infringing material, and the user may then challenge the notice as "obviously invalid."
Followup after actually reading the law. 17 USC 512(c)(3)(A)(iii) provides that a notice includes "Identification of the material that is claimed to be infringing or to be the subject of infringing activity..."
Popcorn Time is the subject of infringing activity, and hence this would be a valid takedown notice.
