I was really hooked by the Eli's trailer and I was waiting for this one. And it wasn't a disappointment.
Firstly, the plot is great ! It really leaves you to want more, trying to decode the mystery revolving around Eli, his illness, and the "clinic" where he is treated. And more importantly, it surprisingly manages to let you still wonder what the heck is going on until the ending twist, even when some keys elements are unveiled. Nicely done !
Secondly, the actors are OK in their roles. No outstanding performance, but there is no disturbing false note either. It's still a bit pity you won't feel that empathetic for Eli and/or his parents. Also, for the role she plays, you can feel it was a cakewalk for Sadie Sink coming from "Stranger Things". On this part, it could have been a little better.
The ambiance mixes supernatural and thriller with a bit of horror elements. And for once, some supernatural elements can be explained "logically" ! Kudos for that ! However, the movie is a bit slow paced and you'll have sometimes the feeling they tried to make it artificially longer.
To summarize, "Eli" is entertaining enough to enjoy the ride and has even enough material for a sequel. Give it a chance ! It deserves it.
