Reviewers see RunwayML as promising but uneven: people like it for fast concepting, abstract b-roll, and having several AI tools in one place with clear expectation-setting. Some call it one of the better text-to-video experiences they’ve tried, and others say results are improving over time. But the sharpest criticism is about value and reliability: several users say prompt adherence is weak, outputs often disappoint, generation can be slow, and moderation feels overly restrictive and hard to appeal.
