Reviewers see RunwayML as a strong but uneven AI video tool. Positive feedback centers on useful concepting, abstract b-roll, and an all-in-one experience with clear explanations and realistic expectations; several users call the results impressive and improving. But the sharpest criticism is practical: high cost, slow generation on some plans, no queueing, weak prompt adherence, inconsistent output quality, and heavy moderation that can block benign content and even lead to account issues. Overall, people find it promising for experimentation more than dependable production work.
