Plot hole: Ruthven is apparently bitter that he has been denied his chance of becoming an immortal vampire after Clara steals the map from him, which is why he attacks Eleanor. But why doesn't he just go to the island anyway? You don't need to be invited - Clara, Eleanor and Frank aren't. Having been there once, it seems highly unlikely he can't find it again - he's a naval captain, so navigation and observation are major professional skills for him. And it isn't hidden or magically protected - the local boatmen know where it is and are prepared to take people there, although they won't set foot on it themselves. He could quite easily have gone there without the map, entered the shrine and been turned into a vampire if that's what he wanted.
Plot hole: Just after Ellis tells Mud about Carver beating up on Juniper, he gets mad and punches the ground and then they start gathering up the stuff Ellis and Neck brought to take it to Mud's boat. They are right on the shore of the river and can see in most directions. Two people are sitting in boats out on the river, just watching Mud and the kids. Very much in visible range and they stand out, one of them even wearing a red shirt. Yet Mud, despite being on the run from cops and bounty hunters, never even notices the two very obvious boats out in the water. If he's running for his life from that type of people, he would have an eye out for them. Not even Ellis and Neck notice them and they just came on the river, and one is Neck's Uncle Galen.

Plot hole: When Bella drops off Jacob and Renesmee at Charlie's house, she says she has to do an errand and will be back soon. She then proceeds to drive to Seattle, which is about 130 miles east and separated by a large body of water called Puget Sound. Being that I live in Seattle, I know that the most direct route from Forks to Seattle involves driving from the outer Washington coast through Port Angeles, then Sequim, going over the Hood Canal (toll) Bridge, before going to plus waiting for and riding a ferry across Puget Sound from Kingtston to Edmonds, and then at least another 25 minutes driving south on I-5 to Seattle. Even if Bella drove very fast (which she could not possibly do the entire way), it would take close to four hours one way, depending on traffic, wait and ride time for the ferry, stopping to pay at the toll bridge, and general driving conditions. Bella would also spend almost two hours in Seattle conducting her business with Mr. Jenks (which include driving through the busy downtown traffic, parking, going through the mall to the restaurant, and driving through the city again back to the ferry terminal) before returning to Forks. Depending on what time she originally left to when she got back home, it would be late in the evening. There are several other ways to get to Seattle from Forks, but they would take just as long or much longer.
Plot hole: In this Australian time-travel fantasy, a college student discovers a one-way time portal that allows him to travel one day into the past each time he uses it. While he at first attempts to rescue his girlfriend from a traffic accident that occurred a day earlier, he eventually travels back 50 years (one day at a time) to save his young grandfather. However, in order to go back 50 years (one day at a time), he'd have to repeatedly climb through the portal over 18,000 times. Apparently, it's not an issue, because the movie just glosses right over it in less than a minute.
