It's 2.5 actually a below average movie.
Negatives: No loki mark anywhere in the movie, anirudh bgm and songs were good when listened normally but in the movie it didn't created any impact, just a total remake of history of violence, unnecessarily added lcu elements where there is no need or space and VFX and CG is below par, no charater is used or utilised properly (Arjun, Sanjay Dutt, GVM, Priya Anand etc.)
Positives: cinematography is good in some fights & it's a one man show of Vijay..
if you're thalapathy fan go and watch for him for your experience that's all.
