Is there any loopholes in Drishyam movie?

Yes, there are several loopholes and mistakes identified in the movie "Drishyam," both in the original Malayalam version and its remakes.

Plot Holes and Inconsistencies

1. IGP's Reconstruction of Events: In both versions, the IGP (Meera Deshmukh in the Hindi remake and Geetha Prabhakar in the Malayalam original) is able to reconstruct the entire plan of the protagonist (Vijay/Georgekutty) with remarkable accuracy despite lacking any concrete evidence or witnesses. This is highly implausible13.

2. Call Records: In the Malayalam version, Georgekutty tells his assistant Monichan that he called him on the 2nd, but the call records could have easily revealed the truth. The director, Jeethu Joseph, admitted this as a mistake2.

3. IMEI Number and Mobile Tracking: The police fail to use the IMEI number of the mobile phone to track down the phone's previous owner and its last location, which would have led them directly to Georgekutty's home. This oversight is a significant plot hole3.

4. CCTV Footage: In the Hindi remake, the police do not check the CCTV footage from the restaurant and movie theater where Vijay claimed to have been, despite these places typically having such cameras4.

Continuity and Factual Errors

1. Blood at the Crime Scene: In the Hindi remake, the blood from the victim's head injury disappears when Vijay returns to the scene, suggesting internal bleeding, which is inconsistent1.

2. Mobile Phone Pieces: When Anju breaks the mobile phone, it breaks into three pieces, but later there are many more pieces seen4.

3. SIM Card Type: In the Malayalam version, Varun uses a Galaxy smartphone with a mini/micro SIM, but Georgekutty finds a normal SIM while cleaning the room5.

4. Mobile Network Availability: Georgekutty mentions there is no mobile network in his area, but later scenes show characters making calls in the same area5.

Other Mistakes

1. Police Procedures: The police are depicted as incompetent, such as not checking for other CCTV footage or not using basic investigative techniques like tracking the IMEI number of the mobile phone34.

2. Character Inconsistencies: In the Hindi remake, the IGP knows details about Vijay's educational background without any prior mention by other officers4.

These points highlight several loopholes and errors in the narrative and execution of "Drishyam."
