I wouldn't categorize Wildlike as a thriller, even though the plot could have gone that way, as for that there isn't enough suspense present in this movie. It's a drama, a well acted drama, with great sceneries in the background. Ella Purnell did a good job playing her character Mackenzie, as well as did Bruce Greenwood playing his character Bartlet. It's a slow paced movie, not much action but it doesn't need it as the story is strong enough to keep you interested. I don't know the budget, probably pretty low, but it's a proof you don't need a big budget to make a good movie. It's worth watching, just don't expect too much thrills as it's not that kind of movie.
