I'm typically very skeptical about films where the writer/director uses it as a vehicle to showcase their acting...because there isn't usually much of the latter to highlight. "I love you both" (the title being a little uninspired) appears to be a collaboration between real-life siblings, and maybe due to the characters being written specifically for them, the script really works. There is a definitely chemistry and appeal between the two leads and their "love interest". The dialogue does fall on the banal side (meaning a lot of it is what you would expect from bored millennials chatting...which is just boring), but some of it also really hits the mark and gives us a glimpse into the motivations of the characters...but there's just too little of that. What we are mostly left with is a "slice of life" in the POV of two likeable, but not very interesting people who happen to be siblings attracted to the same person. That's it. No action, no profound message or anything really substantive. Again, this is a good first try for these actors/writers/directors and I really hope their abilities do get noticed here.
