I mean this in the least condescending way possible... I think that this was a really solid attempt at what they were going for. It was fun, different and entertaining. Granted, not without its flaws, but still should be appreciated for its positives.
I think that this was lacking slightly as far as the story went. We got some seemingly deep but ultimately superficial background on each of the characters and it was presented in such a way that it was nothing of real intrigue or relatability. The chain of events from scene to scene felt oddly disjointed and while the obvious and intended absurdist vibe was present I'm not sure it had enough to balance it out. I think a lot of that unfortunately had to do with the character of Lionel.
While you could definitely tell that the guy was a good actor, it was a little too silly in juxtaposition to the rest of the film to be looked at as a cohesive part of the production as a whole. He gave me much more theater vibes in general and the cartoon Texas accent was distracting (maybe not to someone from the UK, but to an American). The other lead actor did quite a good job with a surprisingly down to earth performance. I would be interested in seeing both of them in something else.
The movie looked quite nice with some actually beautiful shots, had some surprisingly good effects and a fun, absurd tone throughout. This is going to be a polarizing one for some people but I enjoyed it for the most part. 4.5 rounding up to a 5. Would recommend.
